Its saying my version is too old but i just updated it to b1414 what should i do
current version is b1417
Multiplayer can only be played in B1415. You need to update to that build first. Then when you run the game, disable your internet connection to stop the games mandatory update, them as the game is launching, turn on the connection to play multiplayer.
This should be fixed soon! It’s just a server-side setting to my knowledge.
