This prevents the recently discovered ConTracker animation exploit while still allowing players to equip and open their ConTrackers.



The exploit works by preventing TF2 from ever resetting the sequence ACT_MP_CYOA_PDA_IDLE, due to the item being removed from the player's loadout.

The simple fix is to prevent this animation from ever playing in the first place by blocking the cyoa_pda_open command. The more complicated fix would be to reset the sequence ourselves, but that requires gamedata and probably isn't worth it.
