0.3 simulacrum bug (simulacrum stuck)

Hey,

My simulacrum gets stuck in wave 12/13. This is the second time this happened to me. Last time this guy bugged also in the same location. I wonder if it has something to do with the monkeys.

This didn't happen to me before, but it happened now the last 2 out of 2 times (the only times I did simulacrum with monkey charm).
