Reproduceable crash in science labs Win XP SDL version: bcf223e

Just go downstairs to the lab area, or try to teleport either down there or down to the lab finale, and the game locks up for a while and then crashes for me. This is an enemy filled lab so that may have something to do with it, I didn’t clear out all the top floors. likewive I’ve extensively mapped out a bunch of territory at all z levels with artifact map ability.
