Another slew of minor fixes
[list]
[*] Further brute forced a fix for Carter being invisible in cutscenes and being placed incorrectly afterwards
[*] Fixed the blocker for a piece of unfinished content being traversable
[*] Fixed the trigger for the Observatory basement being accessible outside of the building
[/list]
This patch may introduce hitching at the start of some cutscenes. If you notice hitching, don't hesitate to let me know as I'm looking out for it.
