The Roots 2 mod is spawning sprout entities inside my machines.

It seems they despawn when I leave, so it might not cause problems.

This might be related to having the compact machine in a chunkloaded chunk. This chunkloads the machine, possibly stopping them from de-spawning.

I have to same problem..

I also have this issue but mine do not despawn. I come back and there are sometimes 10+ sprouts walking around.

Needs to be verified on the latest version (b278).

This isn't an issue with the CM3. This tells me that the mod's mob spawning mechanics are working and intact. If you don't want sprouts in your machines, find a way to configure Roots 2 to blacklist the Compact Machines dimension, or disable mob spawning in Compact Machines entirely. I am requesting @robotgryphon close this issue.

Per request, going to close this as a crossmod issue until proven that CM3 is at fault for rogue spawning mechanics.
