Not exactly a bug, but I've noticed a lag when playing in a game with about 4-5 players that doesn't happen when it's just me. In the middle of combat, a monster takes damage, and I click on the token, click on the bubble for bar 1, enter the amount (say "-5"), and when I hit enter, I get the pinwheel of death for sometimes 10-12 seconds before I can do anything. I'm running the latest version of Firefox on a 2011 Mac mini with El Capitan, and we're using the D&D 5e Shaped sheet (from one click install, not as a custom sheet). Any ideas what might be causing this? I get no delay at all when it's just me, or even when I've got one other person in the game.
