While trying to surface my boat today ... I hear oh mein gott... an 39 of my crew are DOA! No enemy planes or ships around. If I go to my crew management screen fast enough I can actually see my crew being picked off one by one by some invisible force.
I also have a bug when loading a saved game my boat is running at periscope depth yet my tower crew has magically remanned their stations, and can breathe under water!!! Not too mention if there are an enemy ships or planes near they view me as running surfaced. YET I am at periscope depth.
Gasp!!
Sigh Im running stock GWX ... occasionally with SH3comm.
Umm the date is sept 44-ish.
