Thank you ShibuyaCloth for letting us know that "Selling a Town build won't help you. "
I wanted the Haunted Stable so bad I sold buildings and that didn't help so was reading and re-reading the guides to figure out limits.
Guess that beauty is for people who only have one Stable
On a happy note, I did buy another Bat and am thinking about the Coffin Puppy Bed and Ghost Bench
