I seem to found a bug.
I downloaded the mod and it installed fine. Got the GFO loading screen and everything. Then I started a career as an american skipper and I noticed that all my crew members had insanely high skill ratings. For example this seaman straight out of academy has max stats in almost 3 out of 5 skill categories. Pretty immersion breaking, imo.
I tried an U-Boat campaign next and the crew skills there were at normal rate.
I already tried reinstalling the mod with JSGME to no avail. Could anyone please tell me how to fix this?
