Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Technical Issues Friend on same version cannot join for version dif

Hello, when i host a game (downloaded from GOG) on 1.0.67 version and a friend from Steam try to join (1.0.67 too) he gets a version mismatch error.

I get the same error when i try to join him.

Connection failled : Server has wrong version.
This is frustrating as it tooks us time to find a moment we're both available to play the same time. Our .exe file has the exact same size.
