The game on server Holstentor express is becoming much too slow after html5 conversion. It's almost unplayable! When open any other window like train research and further it takes seconds to display all the items. Also the movement of the map is becoming very slow and stuttering. It's now minimum the 2nd time that one of my server was tried to move into html5 and it's always the same. Please roll it back to flash please!!! I'm playing on MAX OSX 10.15 within firefox. Same is happing in Safari.
