The game is working perfectly however it has a problem with the LOS and LOS AREA tools, more info here https://steamcommunity.com/app/521800/discussions/0/1735462352492629085/ This problem can be reduced including in the parameters steam launcher of the game the option PROTON_USE_WINED3D=1 %command% However although the tools work the map remains black. It's a pity because the game looks great.
