• I checked the MineColonies Wiki and made sure my issue is not covered there. Or I was sent from discord to open an issue here.

What were you playing at the time? Were you able to reproduce it in both settings?

Current Behavior

After warping back to colony on server UUID suddenly started to constantly reassign Minecolonist

  Asked by Mirality to make a report.
  

should be reported to the duplicate fix mod:

Instead of skipping entities with the same uuid's it assigns a new ID and keeps both entities, effectively duplicating a variety of entities, not just ours (which sometimes use the uuid to prevent a duplicate entity on chunkload, as we also manually respawn them)

Mine had nothing to do with incompatibility, I don't use Neoforge nor that DEUF addon which I never heard about, so I'm unsure why mine was closed/merged with this one.

fixed^^
