Ok, this bug has been bothering me for a while.
So, I found this bug when I set the configuration of their lifespan to -1.

Then after that, I began testing it on my new world that I created.
One thing I noticed after playing this mod is that if you create a straw golem, leave them for a while then come back to check on them, they will disappear after a certain amount of time has passed.

Now before you type that "you need to build a fence around them" stuff- yes, I did. But they still disappeared. This bug can be executed by building a fence around the base, spawn a straw golem, leave the straw golem and after a while. Wait for it to disappear.

This is ONE of the bug that I found so far.

#20

Already reported, already fixed in the latest commit (82ff60f), just hasn't made it into a release yet!

I'll get new updates out soon, just working on a fabric port first :)
