Yesterday I was setting up a rather simple map (35 x 35, 0.5 hex grid spacing, DL, no explorer mode, 6 tokens with vision enabled). I had a separate browser tab open to the AIP page for the game for restarting the sandbox (something that I need to do a LOT over the last month or so). After about half an hour, Ctrl+C, Ctrl+V, Ctrl+L, Ctrl+Z and the advanced keyboard shortcuts stopped working. This happened once before about a week ago but it was with a very complex map so that's what I blamed it on at the time. Refreshing and clearing cache did not fix the problem and neither did exiting and re-entering the game. Everything went back to normal after I exited the game and roll20, restarted Chrome then re-entered Roll20 and the game. WIndows 10 Pro and Chrome browser, both with the latest updates. i7-6700K CPU 4GHz 32 Gb RAM Nvidia GeForce GTX 1070 1GB VRAM
