I encountered this Error after killing the 3rd Assembler and closing the 2nd message.

Restart of the complete mission does not fix the issue

Hi, do you also using other mods? Try to disable them first. If doesnt help, contact me again ;)

Hi, if you disable the other mods, you must also play the current mission from the new start. You cant load the mission from your save with disabled mods becasue that actual save still contain the information about the other mods.

ok.....test
