The models for the new heroes appear bugged when watching a replay of a match , and whenever they die the replay drops to 0 fps and crashes , happend with the drifter and doorman models.
I think I may have noticed this too. Watched a replay that had a drifter and doorman, their models were glitching out and getting real big, and at one point the framerate for the replay tanked hardcore, had to quit out.
