Valve update broke custom games
Added 2018-12-07 20:54:35 +0000 UTCA major update by valve has caused a lot of custom games to break, including Overthrow and Dota 12v12. The developers in the moddota discord are still scrambling to figure out is wrong and when we find a fix we will apply it to Overthrow and 12v12. Usually in these cases Valve ends up releasing a patch a day or two later that fixes what problems they caused, so it may be a little wait until everything is working again. Sorry for the inconvenience.
Update: Valve fixed it
