Since the new “Seek & Destroy” update have been implemented, new bug appeared in the naval forces.
Namely, if your ships command bridge is damaged / destroyed, you are unable to initiate a repair.
This has happened to me a dozen times, in several deferent ships. It happens regardless if repairs are set to automatic or manual “press 7 to start repairs” setting.
Note that this only happens when only command bridge is destroyed. Once something else is destroyed, the usual “press 7 to initiate a repairs” button becomes available, and command bridge is repaired, together with the rest of the damage.
