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