So, for the most part, the new Building Blocks Mission works great!.. Until I realized I had already taken the base that the Command Center was supposed to spawn at.
I was able to destroy the shield generators, but now I am left with a unfulfillable mission because there is no Command Center to destroy.
I even attempted to complete a Base Defense to see if that would correct the issue. Unsurprisingly, it did not.
I would prefer not to abandon the base, but I cannot see any other way to solve this issue. Any ideas?
