Sinking for no reason.

[Vonotto]

I loaded up the new NYGM mod and am on patrol....have left port, no damage ect new crew..... aircraft is spoted and I dive to periscope depth.....a few minutes later im at 2 knots and NOT silent running, when I begin to sink I order a return to periscope depth but I continue to sink....I order flank speed and a return to periscope depth but continue to sink.... i blow ballast and order periscope depth which works for a few minutes until I again begin to sink.


ANy ideas what give with this.....it make NYGM completely unplayable for me because I can neve stay at periscope depth for long, even while moving.

Did you hit "C" to order a (crash) dive when the plane was spotted, and then order periscope depth? If so, sounds like the Crash Dive Blues - a known bug. If you order a crash dive by hitting "C" you are ordering the boat to go to a preset depth (stock default is 70m) as quickly as possible. Ordering periscope depth or any other depth before the crash dive is completed can result in the boat continuing to sink out of control.

Bit of a puzzle there mate, I've been testing the latest version and haven't encountered anything like this. Leads me to agree with FK and also suggest the 'Crash Dive Blues' bug. It effects SH3 across the board and seems the most likely cause for what you're currently experiencing. :damn:

Agree with the above-Crash Dive Blues.

Just be thankful there are no escorts hunting you. Everytime it has happened to me, I had escorts searching for me as well, and trying to silently sneak away at flank speed is a wee bit difficult. :damn:

Also what type of boat? Type IXs seem more prone to this than other types, at least for me.

Isn't this a result of the buoyanct parameters coded into the game? :hmmm:

Sinking for no reason is a fact tho, my current experience => just left Pearl Harbor, standard speed setting, cruising on the surface, only a single merchant (friendly as it is bleu) nearby, and no planes. and then... taking ****load of damage and sub destroyed:k_confused:.

might want to look deeper into it :-)

thats SH4 tho.

ps: running the vanilla game with latest updates, no mods or add-ons.
pss: maybe one of my crew is a japanese spy that sabotaged my boat !

I've played a lot of NYGM and never seen this. The boat will not hold depth at 1 kt, but does just fine at 2 and up. I very much like the elimination of the Hummingbird Effect, which is historicall inaccurate behavior. Have to allow for sub motion in planning attacks. I do use the V16B1 patches, which includes the Crash Dive Blues Fix. Don't know if that affects depth control at low speed.

Amazigh1337, were you at high TC? If so, you may have hit an island. That's a common SH4 EBKAC.

[Amazigh1337]

pretty sure i didn't stranded, if you strand (yes i had that before) then the "endclip" shows your nice little sub on a beach.

After a 7th time reloading the game i decided to wait moving, didn't change my travelpath... just waited 2 day's, increasing the time speed ofc, then tried again and... 30 minutes later RL time) i got another huge europian liner on my killstreak with 2 destroyers :rock:game just continue's as it did before:Kaleun_Periskop:

so, no idea what or why... but it is there, no idea what it causes tho, thats all the info i can provide on my part.

[Amazigh1337]

isn't that what a sub sim is all about?

you're submerged, you have a sound contact, you don't know what, you don't know where, you just know its there....:ping:

[Amazigh1337]

ok, it happend again, on patrol at Iowa Jima, not moving, time speed up to 125 for about 5 minutes (RL) at periscope depth.

Nothing being detected, time compression to x1, i turn on silent running, 1/3 ahead, ping for bottom... over 1000 meter, change depth to 30 m (periscope deapth was at 17meters) because i think i would get a better reading for finding ships a 30m depth, as soon i hitted 30meter depth, i take a huge load of damage in superb fast succession and sink before i can even act or hit the blow ballast hotkey. :Kaleun_Crying:

Amazigh1337, I'd guess that you would get more and better advice if you posted in the SH4 forums. OP here is about a persistent SH3 problem.

[Amazigh1337]

ow... my mistake, switching it over to SH4 forums :D

My appologies.
