So, since the last dynamic lighting update a while back, my and my friends campaigns have had a veritable HIVE of bugs. First, everyone in the entire campaign suffers one of two flaws 1; Constant and repeating "A web page is slowing your browser down" This happens across multiple computers, multiple operating systems on any player or GM using Firefox. If using Chrome the error is "you have been disconnected from the server". 2; If the GM refreshes the page, all players get a visual of the map layer as if no dynamic lighting walls are present. 3; There is massive latency. Every player and GM in the groups get lag times of up to several minutes to see rolls, move tokens, or see that tokens have been moved. We have tried every rational action to fix this issue, and have gained no results. Disclosure: We are not playing 5e, pathfinder or any other premade game. We have no API in the background, but have occasionally used CT and Status premade API's Summation this needs addressed as currently Roll20 is basically useless for our games and will force us to find another Web Tabletop.
