TheMarkus1204 said: It is neither! I had Game A (my Numenera Campaign) opened a day earlier AND closed it while exiting the game as always. On the next day, I wanted to open a different campaign and instead Numenera was loaded... it even shows the caption of Game B while loading Game A and after a reload the tab title switches... Happens in BOTH normal AND Incognito... Gauss said: I think there are two issues here. 1) Two different games are open, the first game is refreshed and it will open the second game. I don't think this is a bug, just how things work with the internet etc. For this reason I typically use a different browser for the second game. 2) Game "A" is open, closed, then Game "B" is immediately launched. Game "A" is launched instead. I have seen this happen rarely, but it can happen. I think it is an expression of #1 above, but where the system didn't clear things properly upon closing Game "A". Not sure if this is a Roll20 issue or a Browser issue. But it may be worth sending a bug report into the Devs via the Help Center to have them investigate it. For me it is so infrequent I chalk it up to glitch rather than bug. That still sounds like situation #2, but with a longer timespan. My suggestion is still to file a bug report with the Devs via the Help Center.
