Describe the bug
Spawning of small creatures does seem to be improved, but they might not be adhering to normal spawn rules? Not sure what those are tbh. We've just got a big ol' bunch of snails in our base.

Ah, right. I fixed the spawn rates by switching the bugs to the ambient creature type instead of animal type. I forgot that only animals check to spawn only on grass and not these bugs. I'll fix that tonight.

Thanks!

Just released 1.6.3. They should only spawn on grass now.
