Shortcuts not Working properly

Hello Guys, today i noticed, that Ctrl + Z doesn't affect the movement of a token like it used to. Anyone else have this problem?

Hi Lgs! It seems to be working for me. It moves the token back to where it was before I last moved it. What browser are you using? Do you get the same behavior in a private browsing window?

I can also confirm this issue when drawing walls in the lighting layer and when testing token vision ctrl + L is having issues.

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.
