Team Fortress 2 Update Released

An update to Team Fortress 2 has been released and will be applied automatically when the game is restarted. It fixes a client crash related to material proxies, Scout.NegativeVocalization04 sounds not playing in Mann vs. Machine due to a volume typo, and The Spy-cicle not using its icicle lightwarp, with the latter two as community fixes. The update also revises materials for cp_coldfront and the Taunt: Heartbreaker prop, and fixes several player clip and map issues on koth_demolition.
