The log is here in a gist, several MBs large, and too large for me to read through and find the causing mod.

Game loads okay. Waited a while to talk to some people before I opened a lever. Loading the level did not take that long. But the game view froze before what I assume was the first or second tick after loading, no sounds had started yet, and I also didn't see any animations.

Ow yeah, this is on 1.05. Now updating to 1.10.
