using HF 0.6.0-7

When using Carpenter's blueprint to construct building Yulif will sometimes despawn, and stop constructing his home.

Yulif no longer returns to his home after constructing a building (or wander around at all), and spawns a duplicate of himself. If killed after this he will not respawn naturally. Buildings constructed so far where he exhibits this behavior is mining hill, and blacksmith.

Conversation continued on Discord.
Might be some mod conflict causing the issue.
