I've got the non-Steam version of the game. I booted it up for the first time in a long while after watching some streamers playing V1.06 and thinking the new features were really cool. However, when I launch the game it only patches to V1.05 and I can't figure out how to update it to V1.06. Everything I've found shows how to update the Steam version to the beta V1.06 but nothing for the non-Steam version. How do I update the non-Steam version of the game to V1.06? Thanks!
