Fixed Keyvalue errors reported by the console.

This mutation pack will also get rid of all Special Infected. This should counteract any and all Scripted Spawns.

Fixed Ultra-Realism and Ultra-Realism+ display names.

Fixed loose indentation. If it doesnt eliminate the CI, the next update will.

- Fixed the Ultra-Realism+ Variant being greyed out in the mutation list.
- Reinstated that the tanks will no longer exist. Some maps may be incompatible. Please notify me on any events/maps/finales that make the game impossible to progress with these changes and I will fix it.

Since Tanks have to be killed by a player in order for some addon finales to progress, they are no longer suspectable to instantly disappearing when they spawn. Instead, they will die in one shot. Witches are unchanged.

Readded pills.
