First of all, I run Linux, in case anyone is wondering. When I try to launch the game after todays update, I get the following message:
> An error occurred while updating Tank Mechanic Simulator (missing executable):
> /home/[username]/.local/share/Steam/steamapps/common/TankMechanicSimulator/TMS_Manual_EN.pdf
My username is just all lowercase latin letters, and the file doesn't actually exist.
Just putting another PDF with the same name there leads to a crash, and all steps suggeested by steam didn't bring any change.
