(I'm submitting my console log via pastebin because I keep getting an error when I try to post otherwise.) Hi Keith, Thanks for the reply. I just tried again in Firefox, and then in Chrome with cache cleared, extensions and plugins disabled via command line switches, and windows defender firewall and antivirus disabled. Problem persists, so here's step 4: A detailed description of the issue. The more information you can give us, the better able we'll be to fix the issue promptly! Decks do not display correctly in my primary game. Clicking the show deck button creates a collapsed box in the lower right corner of the window. Hovering on this box expands it into a blank panel, with no card backs visible. Sometimes, I can see either the shuffle button or the other deck controls. When this happens, clicking deal will allow me to distribute cards to players, which seem to function normally. Right now its only displaying the blank panel, so I'm not able to deal at all. In the settings, there is an image set for deck backs, and changing the image does not fix the problem. New decks and the default Playing Cards deck are all affected. Issue persists if I am logged in as GM or as a player. This issue only affects my primary roll20 game which was created in 2015, and any copies of it I made (backups when I was experimenting with Pro and other sheet types). Brand new games are unaffected -- when I create one, decks function normally. This leads me to believe that something in my game got corrupted. Step by step instructions on how to reproduce the issue. 1. Launch my "Adventures in Phandalin" (<a href="https://app.roll20.net/join/527009/CzBiDA" rel="nofollow">https://app.roll20.net/join/527009/CzBiDA</a>) game. 2. Switch to the collections tab. Click the Show button on the playing cards deck. 3. Tiny white square will appear in the bottom right section of the map (this isn't visible against a white background). Hover to expand the empty cards panel.
