Seems to be an issue with Gourdian Armor and what looks to be Iron Golems? Not exactly sure how, but it appears to be causing them to tick maybe? Here is the log.

Or perhaps entities are spawning with it equipped?

Thanks, mate! I'll be looking into this tomorrow!

The issue is not strictly related to golems. In my case the ticking entities that cause a crash are wither skulls (both blue and normal ones).
