Please make sure all players have exactly same git versions of their in-game mods (RA, CNC, D2K, TS, RA2). Version numbers are formatted like 'git-e0d7445' etc. and can be found in each mod description in the mod selection menu.\n\nFor this compilation, the version numbers are as follows:\nOpenRA version: $OPENRA_GITVERSION\nRA2 version: $RA2_GITVERSION\n\nHave fun!\n"
