I'm uncertain if this is a bug per se (and can move it to suggestions instead if need be)

But Crystal Cartography unlocks cannot be applied to personal / temporary battlefield circles!  A bit unfortunate, given how unique of a feature that is to the battlefield circles.  I feel if they were available for temporary circles, they would allow for some more flexibility in specific locations without the need of EM help.

:pray:

Not a bug but I'll keep it in mind as a possible future addition.
