Hi Intruder, for these messages usually it means that the periscope 3D model in the turmxxx.dat is missing the zoncontroller, or has the wrong zone number.
Basic.cfg has a zone number for the periscope(s), and if that zone is not found in the turm.dat or turm.zon, the game thinks that the periscope is destroyed and gives this message. I hope this helps
