Critical Tripping or falling prevents you from interaction.

[Technature]

wait you're saying YOUR tripping sequence stopped everyone else from interacting too ?

A few people mentioned that it stopped when they were supposed to fall but didn't (the clown stumbled, I think the captain tripped on blood, etc.).  Anyone that hadn't fallen yet could still do things.

I have the strong suspicion this was a case of the server throwing a hissy fit, not an actual bug.

I don't know whether to hope that was the case or not...
