unable to proceed through infirmary door in Tau

[Romulator]

Glad to hear you got it solved, though I am sorry I didn't see this sooner!

A Steam File Integrity Check could have probably fixed that if there was an error with 04_02_tau_inside's script file (for example, an incompletely installed file), and that to me is most probable since this is not a known issue for a majority of users.

Nonetheless, glad to hear it's solved. Considering where you are in the game, I'm sorry if this issue really hindered progress, but keep at it. Hopefully the issue won't continue to arise!
