I am having an issue maintaining depth in my u-boote. I have NYGM-Tonnage War loaded.
While at periscope depth, my boote cannot keep depth at speeds under 1/3 knots. It sinks if speed is 0 and falls below periscope depth. I cannot maintain depth while submerged at any depth unless I keep the speed above 1/2 knots. Kinda stinks to run at higher speeds just to maintain depth and all this time battery is draining quickly. Can't run silent while trying to keep even depth. I nearly had boote sink to crushing depth while I was at 64 time compression! Saved it when I saw depth gauge plummet!! Only happens when I am submerged and does not happen when I am surfaced.
There is no damage to boote nor has there been any to the dive planes.
Please advise.
