Dear Settlers,
In the current game version, the problem concerning blocking in the game has been fixed.
This hotfix maintenance has restored the blocking so that buildings can no longer be placed on top of each other. However, it has not fixed buildings that are already on top of each other. You may still experience overlap in the game and we ask that you manually move buildings and generals apart. If you do not do this, you may still experience problems (locked zone, sleeping buildings, etc.).
With best regards
Your "The Settlers Online" Team
