Building of Anti-Missile-Turrets in a shipyard, after deploying there are 3 Stages that happen. First stage: Turret works as it should. Second stage: Turret just does nothing, even after recalibrating the ai module or un and redock every parts of it. Stage 3: Turret does nothing as in stage 2, after turning the turret out of field of view or after quit and rejoin the "turret-head" is invisible, but still physical. When i enter the turret-base the base is seen and useable, the head is still invisible, after switching into the head wirh arrowkeys i see the head and the rest is as i woud be in a clear sector without the marks for other sectors, there i´m able to edit the head. After switching back to the turret-base, the head is invisible again, but still physical, and the rest of the sector has to be loaded again as i would have newly entered the sector. If i try to undock the head the game freezes. Sometimes after ignoring the problem the turret-head and base just dissapear. If i try to undock the head the game freezes. I also got ships builded in shipyards wich just dissapear after some time and/or restarts of the server. In every case there are no traces in the logs, by freezing it looks like i exited the server just like klicking exit...
