Uncontrollable dive bug. HELP!

[Volkier]

It's February 1940, and I've stumbled into a bug that I seem to not be able to fix in any shape way or form. Every time I try to manually dive to a certain depth, my boat goes into an uncontrollable dive until I hit the floor of the Ocean. Spamming depth to for example 40m when I'm at 80m doesn't do anything, and keeps me going down. The only way to survive is to get to periscope depth - or engage engines outside silent running - both of which is suicidal when one is surrounded by a dozen or so pissed off destroyers who were escorting the cruiser I just sank.

Can't seem to find any fix for this anywhere. The links suggesting mods are all broken, and I find it hard to imagine a bug like this has not been addressed yet. Can anyone suggest a fix for this? I'm at a loss as to what to do :(

Volkier!:Kaleun_Salute:better tech assistance than I should arrive shortly!

I'm trying to thrawl through these boards to find a solution, but with destroyers circling above and depth charges going off dangerously close, my crew is panicking, oxygen is depleting, and desperation is setting in :(

Apologies in advance if this has been answered before (I'm sure it has been).

Have you a link to the mods you are referring to?

You may well need to put on a few revs to gain control even if it raises your signature noise level.

One tip would obviously be to engage well escorted ships only whilst in deep waters.

Welcome Aboard :sunny:

Not playing any mods. Playing on Vanilla, and loaded several games now trying to figure out what the heck is bugged. Seems like the first boat upgrade screws me over - the initial one's depth control worked perfectly at any depth and any speed. The upgraded boat seems to overshoot every single low depth reading (admittedly before leveling out) and after 60 or 70m depth just keeps going down if I am stationary or moving at slow ahead. I can bring myself back up by hitting periscope depth or surfacing the boat - but as mentioned, a diving mechanic bug in a sub simulation game is kind of.. yeah..

Lots of re-loading at port and sailing back out into 200m deep waters to try different realism settings too. Doesn't seem to have any effect(s). Navigator's skills don't seem to affect this in any way (other than diving deeper before imploding). I can "theoretically" keep my current depth by spamming periscope depth and the depth I want at every half a minute intervals, but that completely kills whatever immersion I have left after overlooking everything else, and the whole point of playing this game, since it goes against basic boyancy principles and physics (the boat may not dive to an accurate level, but constant pressure vs mass in the ballast tanks would maintain that inaccurate depth. That might vary pending on your speed and the angle of attack on your ailerons, but that would be tweaked in those situations)

On subject - deck awash doesn't seem to work on the same upgraded sub. Setting depth to 7m refuses to allow the boat to get below 6m - which doesn't really 'awash deck' unless there are swells, and setting depth to 8m takes the sub down to 10-11m - which puts the bridge underwater (you can also still walk around the surface deck of your boat like normal, even though you are fully submerged at pretty much the periscope depth. On that note, setting the depth to 6m would take the boat down to 10-11m in a similar fashion if you reverse at emergency speed.

So my question(s) are:
- Is there a known fix for this?
- Is this the only type of the U-Boat that is bugged, and do I suck it up and wait until I get an upgrade which works?
- Do I re-load to the starter sub, and just refuse whenever I get assigned a new boat, since that one had none of these issues.
- Do I simply give up and go back to SH4 with all the crashes or SH3 with dated graphics.


Surely I can't be the only one with this problem :"(

Is this the old problem where you get to a certain depth under control and then you go past the point of no return and cannot stop it from crashing to the bottom?

Has this got anything to do with the patch ‘Sub on bottom fix’ in the TDW’s GFP.

There is also this patch link to ‘Depth Keeping Problem by TDW’

This could be useful to anyone also who is using steam.

It's not really a point of no return. I can return easily if I give the order to go to periscope depth or surface the boat, but order for any depth below periscope tends to not have any effect whatsoever, and I keep "sinking" (which is the wrong term to use, as the boat is clearly still under control as I can still surface normally).

In the same breath, if I set depth to say - 40m, my boat would dive to approximately 60m before coming back up to 40m. Ok, I can blame that on incompetent crew under pressure who did not pay any attention to the depth meter and didn't start leveling out early - but shouldn't someone 'turn the tap off' and stop flooding the ballast tanks when the navigation officer calls out "we are at 100m sir" when we are supposed to be at 60m?

Will try that fix - thank you :)
Kind of sad and confused as to why such a critical bug was not fixed through game patches to this date :\

EDIT:
Yep - that fix is working like a well oiled diesel pistol. Danke-shun! :D

EDIT 2:
Also, to clear things up and re-reading my earlier posts, "physics" was the wrong choice of words to use. I do realise that as you dive deeper, your boyancy decrease as the volume of your ballast gets squashed / compressed. This would therefore be a realistic behaviour under a certain depth if the boat was a hollowed out brick, that was boyant but pushed below that point (or another example, filled with corpses instead of a live crew). However, in practice, the realistic response of your crew would be to play around with the ailerons and balast tanks to level the boat out at any depth at any speed, adjusting for those variables (speed and depth), and while it might be harder to keep an accurate depth the deeper you go, you would remain at that rough depth due to your crew's actions and their effects on the boat. Obviously up to a certain point where even blowing ballast is insufficient to create enough boyancy to counteract external pressure. Just thought I would mention this, as I can see how my above posts can be interpreted in a way that makes me look like an idiot, whereas I at least try to pretend not to be one :88)

Such is the gaming/simulation world we live in.

You have to draw a line between was reality and what is in the game.:hmmm:

Aye well, thank you everyone. I'll have a look if there are any other fixes amongst the mods here :Kaleun_Cheers:
