We have a standard card deck, and have had no problems with it for a very long time. Recently, players have been unable to see the image on their cards, and GMs haven't been able to click on theirs to see it either. Initially this was just the one player, and we got them to clear their cache, check browser extensions, etc. Now it's spread to multiple players, and we don't know how to fix it. Example from today: GM (using Chrome) dealt cards onto the table. He couldn't see them. Two other players (using Chrome) couldn't see them. One player (using Firefox) couldn't see them. I (using Chrome) could see them. Out of those who couldn't see them, some saw nothing, whilst others saw a broken image icon.
