artus topside stuck at the end

[magalina]

After I destroyed the cannons, I got a message that I had to go to the landing platform to meet Jan, but the door at the end of the top floor in the repair bay is still locked. I tried to use noclip mode, but when I arrive at the platform Jan and 2 other NPC's are frozen, so I can't end the level. Is there anything else I need to do before the door opens? I killed everything and destroyed all cannons and robots.
Thanks

Yes i have, but I installed it after I got this problem.
Guess this means restarting ...
