When I close Factorio (experimental 0.17.66) it will not close completely for some reason. With everything I tried like closing with alt+f4, closing it by clicking "exit", closing it with task manager the game is still running in the background. When I go to steam in my game-library I can see that it's still running. There is no window hidden anywhere, factorio is closed ... but it's actually not... The task-manager also tells me that it's still running somewhere in the background but I can't close it with the task manager and not even with the taskkill command in the cmd.
The only way it closes is when I restart my PC which I obviously don't want to do all the time. When the game is running on steam it means that I can't even open another game instead.
It's really annoying though I think it could be a problem with steam since I had this problem several times with other games already. Maybe someone can still help here or knows whats going on
