Just a thought Nik:
You’re giving others sensors to your German U-Boat Compilation with the last mod. No wonder you lost something on the road
Second, the German U-Boat Compilation sensors have different values than GWX ones (assuming you are playing GWX). So unless you give German U-Boat Compilation sensor.dat same GWX values, you are not playing GWX anymore!...
Quite complicated to perfectly adapt so many mods to a data base like GWX without breaking something (well should say many things)...
Last advice would be to deactivate your German U-Boats Compilation 2 (only VIIB & VIIC models by WISE) unless playing VIIB & VIIC only first turm career. After VIIC first turm it will certainly CTD as the mod is not finished. Well here i got CTD anyway.
