I'm afraid I messed up.
I'm using ElvUI on the PTR, and I forgot that Carbonite has a problem with ElvUI when you try to combine the maps. I just fixed it (by turning off ElvUI's minimap control) and it works great, as far as I can tell, anyway. No errors yet, which is a
GOOD thing. But, I've got a clock
inside the minimized map, and I can't get that straightened out seemingly no matter WHAT I do. Weird.
I apologize for the wrong information, but at the time it wasn't wrong. It just turned out to be wrong when my mind finally remembered that Carbonite and ElvUI have a problem when you try to combine the maps, simply because ElvUI takes control of Blizzard's minimap.

Here's a screen shot. I don't have "ctrl" pressed, so, no clock in the minimized map.
