Older Custom Quick Battle Maps Crashing v2.12 Out To The Desktop?

[tankgeezer]

Got an older Custom One-Off map that crashes or hangs under v2.12?

I've found that opening them in the editor and re-saving them makes them operable again. I usually make at least one unobtrusive change first; such as, plugging in a single tree or bush somewhere.

I have had the same experience. But I haven't had to make any changes before saving to fix it. Just load it then save it.
