Map Issue

So I was just trying to upload a map for a page. I got it from Czepeku, and it's size is 6300 x 8680, so obviously pretty big. When I uploaded the map I attempted to do so via dragging and dropping it directly to the grid while it was on the map layer. After several seconds of loading it didn't show up, but when I click the little tab at the top right to bring up all my map pages, it shows the map as being there in the thumbnail. Worse yet, all of my other maps are now gone, too. All the tokens and such are still there and it shows the maps as being there in all the other thumbnails. I'm at a loss here, any advice? I did delete that page but that didn't seem to do anything.

I've got the same issue, seems to just be a roll20 bug lets hope its fixed soon <3

Same issue here as well, but also for tokens not being able to be dropped onto it

Same here, maps and some token just stopped working. 

Same here

I've got a similar situation to Ryan A. When I logged on to one of my current games 30 minutes ago, the maps show in the thumbnail but have ALL disappeared on the game screen. This is from a campaign I have built assets/maps for and run for over 10 years with never a problem like this.  Maps in other games seem to have the same problem.  All the tokens are still visible, as well as the dynamic lighting.  HOLD UP!  I just checked again and reloaded for the 8th time and the maps have finally returned magically (for the moment at least).  Will they remain or disappear in the future? Only time will tell I guess...
