Proton Hotfix was the only version that would run after trying 9.0-4 and Experimental first without success. Aside from the graphical glitch in the start menu that doesn't hinder anything, the only problem is I can't get non-workshop games to run using -mod=mod/"HIP.mod" -mod=mod/"HIP_Patch.mod" to get them to be recognized like another submission noted. I still have HIP installed but haven't figured out how to get it to work. Workshop mods work fine, though.
