Every time I try and open this campaign I last used on the 7th, I get this "internal inconsistency" error, leaving me unable to work on my campaign. Before that, whilst playing it on Tuesday, once I switched from one map screen to another, it was stuck on the loading black intermittent screen with the roll20 logo. I kept going with the campaign as much as I could with only using the chat. Now I can't even do that, nor can I prepare for my game on Monday. If it helps, I'm running on Windows 7 64bit, Mozilla Firefox.
Edit: When I refresh I get the second image, it seems to downgrade the already bad quality that the editor is in.
