Your Units returned to your Bunker because one of the following situations occurred while your Units were on the way to the Tapsite:
- The Tapsite disappeared from the Map as no one сaptured or attacked it for more than 24 hours;
- The Tapsite ran out of Resources;
- The Tapsite was captured by a member of your Clan;
- The Tapsite you were trying to attack or recon became vacant.
In all these cases your Units do not travel back to your Sector but are immediately sent to your Bunker.
