When I played as a Samedi, I encountered this bug where the doors wouldn't unlock in the temple to get back in the cab. I looked and it turns out someone put a logic_timer in the map that would refire the Set Temple State script which would relock the doors. So they were unlocking when talking to Ming Xiao, then relocking when you walked out.
Grrrr, hate stuff like that. Oh well, it's fixed.
