Minecolonies version

version 1.12.2-0.9.27-ALPHA-universal

Expected behavior

• Change mining level on mine in order to be able to mine materials
• Miner moves up to selected level
• MIner continues mining at normal pace

Actual behaviour

• Successful change of mining level
• Minger moves to selected level
• Game crashes 5 minutes later

Steps to reproduce the problem

1. Have a level 3 mine
2. Set the level for the miner to mine at level 4
3. Wait
4. Crash?

Looking at the crash report it seems to be the miner is taking damage and it is not registering?
I would appreciate the help, as I would not like to lose the progress I have made over the past week.
Code: https://paste.dimdev.org/esinuturoh.mccrash - This is the crash report it fed me when it crashed.

Thanks!

Already fixed, update to the latest alpha version
