I think the problem is german U-boat compilation II. ( models by wise ) they are not finished. Alltgough there is a Turm type VIIb 2, there is no Turm VIIC 2. So if your Basic.cfg automatically changes the Turm to type 2, then CTD. You must disable wise boats just before autumn 1942 or the date in basic.cfg when Z01=2 ( Turm change ) and continue forward with your career with original VIIC in u-boat compilation mod. Wise updates his thread on continuing work and when released his VIIC model will be playable till 1945.
