I was working on roll20 this afternoon, and had built a large labyrinth with almost 17 rooms. when we went to log on this evening alot of the elements had vanished from the screen. Funny enough some of the elements were on one page but not another. All the campaigns on the Dev Server are affected this way, I have cleared the cache and cookies and checked all the add-ons, uninstalled Firefox and reinstalled it. All members of our game are also not seeing many of the elements that were there. This is quite disturbing considering the work I put in. I am currently running a Intel I7 processor, 8 gigs of RAM, 1Gig video card not sure which one, windows 8. Let me know if you need more info, my players and I were suppose to play tonight but have had to postpone.
