Minecolonies version

minecolonies-universal-1.11.2-0.8.1784
Forge-1.11.2-13.20.0.2310-universal

Expected behavior

Start a building project, a builders hut

Actual behaviour

when I start the project and add all the required materials into the hut's inventory
The builder collects the items and starts working on the build.
but no blocks are breaking for the ground and no blocks are being placed by the builder but the resources are being used up.
the builder says the build is complete and restarts it all over again and uses more resources

Steps to reproduce the problem

start building a builder's hut

Are you using any additional mods?

i remember that this was a bug in 1.10 too and already fixed some time ago
like 1-2 month

Should be fixed if you add "EntityCitizen" as allowed griefer in the config
