CTD when sonar ranging
 

Greetings,

Just recently got back into SH4 and loving it all over again, but have run into an odd issue that I managed to reproduce, so I thought I'd ask here for answers:

I'm on patrol in the Sea of Japan in August 1943 with a Gato out of Midway. I came across a line merchant at night in rough seas and set up for an attack. With the waves bucking me around the stadimeter is more useless than normal. I'm trying to get a sonar range, so I use the orders bar to ask my sound guy for a check --- SH4 has stopped working, CTD.

Now I've used the sonar to get ranges multiple times, so I wrote it off. Reload the patrol the next day and try again. Sink a couple merchants (even manage to get a sound range from my sonar guy on one of them), when one dark and rough night I again come across a lone merchant. Same scenario, set up, ask for a range, ---- CTD.

Now, I tried to isolate the common factors: Both times it was night, rough waters, and I'm at PD. I ask for range from the orders bar, not by pinging myself. The second time it was a Ryun Maru (name is probably wrong but it's something similar, large fore and aft masts, dazzle camo job)

Mods:
TMO 2.5 and patch
RSRD 5xx and patch
TMO visuals for RSRD
C/D sonar fix
IJN Radar fix
Zero bomb load fix
ISE v3 for TMO/RFB

I should add, I'm also running the LAA patch

Any clue what's going on?

Someone more familiar with the game will have to "spy" your mods, because I'm not familiar with a couple of them - but, you could back them off one at a time and try that same vessel with sonar ranging and see if it works. BUT (another "but"?? I'd say something, but I won't), since the ranging worked on one ship, but not another, there may be an issue with the ID of that particular vessel (Type= or Class= line in the MIS file or cfg files). If you put the external camera on, can you get close enough to visually identify the ship yourself? Did you ever get a "lock" or an "ID" in the periscope? If you do, and it didn't CTD, then that's not the issue...

The game is looking up that ship, finding nothing and crashing. Not really good error handling routines in SH4. But it does not allow us to ignore errors so that's a good thing!

welcome aboard!
