- Fixed Minigun not playing spin sound after you stop shooting, but still hold right-click
- Fixed Minigun being forcibly removed while shooting or spooling causing you to be stuck moving slowly
- Minigun slow movement no longer affects vertical movement if Custom Roles is installed
- Minigun animations are now networked to help with janky animations during lag or high ping

Fixed spectators being treated as players during "Meet the Randomat!"

- Added a server setting: `tf2_weapon_collection_auto_reload 0` which turns off TF2 weapons auto-reloading
- Fixed Sandvich health HUD prompt being stuck on screen

- All TF2 melee weapons now:
- Use lag compensation, so it's much easier to hit with a laggy connection
- Have less range to compensate for this
- Break breakable glass
- Have an impact effect where you hit
- Have blood effects for hitting players or a body
- Play the correct impact sound on hitting a body
- Properly play sounds from the weapon rather than the player

- Doubled damage of the syringe gun
- Made Syringe Gun upgrade description more clear
- Fixed upgraded Lollichop applying the Pyroland texture to all players
