Well, my first problem with my own mission.
I have 3 cruisers inbound here till now. 1 is friendly, 2 are hostiles. When the hostiles are ingame from the beginning on, all works fine. They use their beam weapons etc. the friendly cruiser comes in after a short period of time, and here all is fine, too.
But when I give the 2 hostile cruisers a time counter to jump in, too, all 3 cruisers do not fire a single shot. They even do not have any weapons. I cannot target weapons, and I cannot target subsystems on them. I gave them "beam free all" like I did when the hostile cruisers are ingame from the beginning, but when they get a counter to come in later, nothing works on any of those cruisers.
I have no glue what this means

What can I do? Perhaps somebody wants my file and take a look?
