Minecolonies version

minecolonies-1.12.2-0.9.1-RELEASE-universal.jar

Expected behavior

Make guard tower, employed guard will act as normal.

Actual behaviour

Spamming server console error message, please see console log it was too long and looked terrible pasted here.

Steps to reproduce the problem

  1. Put minecolonies on a server.
  2. Build a guard tower in your colony.
  3. Issue begins to spam the log, changing whether guard is automatically or manually assigned, fulfilling any request and changing from knight to ranger does not solve the issue.

Updated to minecolonies-1.12.2-0.9.86-ALPHA-universal.jar a couple of days ago and no longer experiencing this issue. We are however experiencing barbarians that are invisible at times, I will just attempt to replicate this issue again today and post a new issue for it.
