My problem: I cannot interact with my maps, tokens, fog layers, or really anything. If I add tokens to a map, they do not appear unless I refresh the entire page. Nothing I add to the scene appears unless I refresh. This is not currently playable or usable. I have some suspcicions where my problem came up: I think that the adv. fog of war layer has a feisty bug. Here is what my editor looks like: My details: Chrome, v 62.0.3202.94 (latest, I believe) Problem persists on Firefox v 56 as well Windows 10 Home 64 bit Javascript is enabled Malwarebytes (free version) as antivirus, shouldn't affect browser Addons: only one, BlueJeans Meeting (for work) My background to the problem: I recently added the Roll 20 Pro Map Pack from my game's landing page. When I went to one of the maps to look at it, I used the reveal areas tool. The map didn't have fog or adv fog, so the map prompted me: Would you like to use fog? I turned on Adv Fog. Everything broke after that. Things I have tried: I removed the Map Pack and all maps involved (thinking it was bugged) I rolled my game back to yesterday's version I have tried deleting the bad maps, switching to other maps, and creating new maps I cleared my browser cache and temp files These did not solve the problem. Here is currently how I recreate this issue (CONSOLE included in screenshots): First, I load the game fresh, with my last map viewed being a currently active map for my group. This looks fine. I add a new page, looks like the console says something is wrong "Uncaught TypeError: (d20.Campaign.activePage(...).get(...) + (d20.Campaign.activePage(...).get(...) / 2)).toFixed is not a function at m (app.js?1510076098:31)" The zoom is the first thing I tried to fiddle with, it does not zoom correctly (note the hexes are the same size as the previous screenshot) I add a character to the view (note the console logging it happens). I see nothing: I try to reveal the fog, and the reveal fog box does not go away. It also throws more errors of the same kind (50 of them, this time): I switch to a new page, the view is now broken on this page (note the page-toolbar is back to the map I first landed on): If I try to return to the map that I created for this test, you see that it is now absolutely monstrous: I opened the location the error is coming from, in the JS file. It seems to be trying something with the fog of war (but I am not entirely sure what is going on here): This is the original popup that I clicked when it all started: If I refresh the page and zoom out, here is the view (note how dark it looks, with lines running through it): Please advise.
