Solved [HELP] Incubators not working.

Problem solved.

Is there some kind of limit to how many slimes you can hatch? I've only hatched four.

Slime hutches can only hold 20 slimes. If you have that many, new ones won't hatch from an incubator. I don't believe creating areas within the hutch should cause any issues though.
