Depth keeping.
 

Is depth keeping in OM with OMEGU a commen problem?

It shouldn't be. What are your circumstances; i.e. how fast are you travelling? Is there a chance you've taken some damage that wasn't fully repaired? That sort of thing.

In NYGM for SH3 they had what they called the "Anti-Hummingbird mod". If you travelled at two knots or less you would slowly start to sink, which is realistic. I don't know if Lurker put anything like that into OM, but he may have. Also sometimes damage can have a negative effect on bouyancy, even if it has been fully repaired.

No, it wasnt any special or extenuating circumstances. Normaly when I put to sea for the patrol I do a crash dive when I get into 50 meters of water in order to work out the kinks, so to speak. It might have something to do with my mod order. I'll post it though nothing jumps out at me but maybe you can see something.
