Is there an existing issue for this?

• I have searched the existing issues.

Are you using the latest MineColonies Version?

• I am running the latest beta/release version of MineColonies for my Minecraft version.
  I am also running the latest versions of other mods that are part of my problem.

Did you check on the Wiki? or ask on Discord?

• 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.
