Minecolonies version

version 1.12.2-0.9.104-alpha

Expected behavior

Barbarians will appear and colonists will fight or be killed by them.

Actual behaviour

I get the alert of the upcoming attack (in red) followed by maaany repetitions of "Only 2 barbarians left! Only 1 barbarians left! You successfully defended your colony against the Barbarian intruders!" Over and over again. 2, then 1, then success, then 2 again, then 1, etc.

Steps to reproduce the problem

1. Get red alert
2. See no barbarians, but recieve repeated messages about decreasing numbers if barbarians
3. Have chat spammed by these messages
4. Profit?
