When adding mods - first test stock SH5 v1.2
If all ok - add one mod at a time and test.
beware of mods that overwrite other mods (here that file that is overwriten may be needed in its old form by the first mod)
Any mod that changes your boat by adding or removing equip (items) must be installed in the bunker.
Any that change you career (camapign and crew mods) need a restart.
If you get ctds:-
have you just added a mod
have you edited your options
did a sound play (or try too)
did you just meet a convoy (or ship/aeroplane)
are you close to port (kiel) within 30km
did you just meet a convoy with TC set to superfast (over512)
....
