I have made a map that places a custom command center building using the "Set Starting Units for Player" action. The command center itself uses a 3x3 contour footprint with slight modifications (it can only be placed near resources).
However, about half the time the command center footprint doesn't work -- I can build right on top of it! Does anyone know why this is happening/how to fix it?
All right, after some more hours on the issue I figured it out. Turns out it was something unrelated - because this building is also a builder unit (using SCV - Build), while it is in the process of building it seems to think it has no footprint and can shift-queue a building on top of itself. After I reset the footprint and changed only the bare minimum for it to function, it seems to have realized that doesn't work.
Thank you for your feedback - it at least got me looking in the right area to look at and revert the footprint! I really appreciate your help.
