Hi, I just finished being GM for my game. We experienced lag issues for all my players and myself. Not only that but at one point all my tools stopped working one after the other and then various parts of the screen went black. The turn tracker was the first to disappear, then the tool bar, then the chat went black and dropped out, then the map went black. I retained the voice. I tried to just refresh the page in the browser but that did not work. I then cleared the cache, and tried refreshing the page again. Still no go. I then restarted the browser completely. I managed to log back in and continue but it was still very slow and lagging. I use MacBook Pro (13-inch, 2020) Big Sur version 11.2.3 with Safari, with a dock and second screen. I have not had these issues before. Thanks very much.
