**FIXED** I opened a map page that was previously existing from my Yawning portal pack and it shows as all black. I checked another one and it also shows as all black. The third one I am working in looks fine. Two days ago, all 3 of these maps looked just fine. I did not change any map settings on any pages. Has anyone heard of this happening? How should I troubleshoot this? Okay, I'm totally an idiot. I was using Ctrl-L on my map and when I moved to another map it carried that command and since there was no PC on that new map I could not "see" anything. I removed the "token view" and everything is back to normal. False alarm. Left this here though just in case someone else has that problem.
