Windows [BUG] Baby slime spawned outside (infested) floor in the mines

[Frigolit]

I was killing a couple of slimes that were mating on an infested floor in the mines. Attacking them caused them to get pushed into a corner, and right before they died they had a baby which spawned outside the map, preventing it from being killed and clearing the floor.

Version is 1.5.6 hotfix #3 and if it makes any difference this happened in multiplayer with myself on Linux and the host on Windows.
