tf2 update apparently
An update to Team Fortress 2 has been released. The update will be applied automatically when you restart Team Fortress 2. The major changes include:
Fixed matchmaking sending players to out-of-date servers
Fixed the server browser showing an incorrect player count in MvM games
Fixed a crash that could occur on map change if another player was being healed by the dispenser or payload cart
Fixed a rare server crash when firing hitscan weapons
Fixed MvM intro video not playing on some Macs
Fixed the sound precache string table being nearly full in non-MvM games
This was causing the "error writing string table baseline" and "failed reading message net_SetConVar" errors
just bug fixes
maybe hidden stuff
probably not
