Conclusio: If the Hex positions in the data files like
AI_Sensors.dat
GUNS_SUB.sim
Cameras.dat
Sensors.sim
Sensors.dat
NSS_Uboat7b.sim
NSS_Uboat7c.sim
NSS_Uboat9b.sim
NSS_Uboat9c.sim
NSS_Uboat9d2.sim
NSS_Uboat21.sim
have been changed by modders and these changes have not been considered in the Randomized Events.cfg, this MAY lead to a CTD in conjunction with Sabotage & Malfunction.
So it's not the Sh3Cmdr in itself that causes the problems.
