Repulsor Field does not display properly for > 1 colony

[Clint Herron]

Description of the Problem: When placing the Repulsor Field on a region with more than 1 colony, the field is not sized correctly and overlays the number on the colony.

Expected Behavior: It should use the proper graphic no matter how many colonies are on the region
