after this lhc update every time i shift+enter to make it full screen works on the 1st try but when i do it again to transfer ores and etc to a mule and i click shift+enter it starts to lag so much and when i let the arrows go it keeps walking on it's own...this never happened before this lhc bugged update..i installed again and i restart pc and again it happened... dunno if it's just me but i never had this problem until LHC update....
I think the issue only occurs if you enter full screen Are you able to try play Royals in a bigger client window instead?
