The changes include the following:

- Fixed several Mutations that use SaveTable() when the map transitions, it should no longer retain data from the previous map when you vote to restart or change campaign.

- Updated the HUD for many Mutations that use it. It should now prevent errors when trying to search for a survivor who hasn't spawned in yet.

- Added "Altered Genetics" officially, SI only that change their type when spawned. So a Boomer might count as a Spitter when killed and drop goo, etc.

- Removed the Prototype list from the menu, it was accidentally added in the previous update.

- Updated all VIP Escort modes:

The Survivor no longer loses his name and turns into a duplicate Bill if all survivors are incapped when the map restarts.
Made the VIP spawn with a medkit at the start of the first map only. No medkits will be given if the map doesn't allow medkits or if you've made it to the next map.

- Updated all United We Stand modes:

(United We Stand Realism): Added the missing mission files so the official L4D1 campaigns will work as intended now.
Made the L4D1 survivors spawn with a medkit for coop modes at the start of the first map only. No medkits will be given if you've made it to the next map.
Added a failsafe to force the Cvar "sb_l4d1_survivor_behavior" to 0 if it isn't already set. This prevents the L4D1 bots from running away on their own.
Fixed an issue with Zoey's item data getting lost if the map restarts due to all survivors being incapped.
Removed the extra weapons and items Zoey drops when the map restarts.
Added talker responses for the L4D2 survivors during the plane crash at Dead Air's finale.

The changes include the following:

- Fixed an issue in the ZSL Campaign Mutations that caused the survivors to not warp to the ending saferoom after failing all 3 attempts.

- Changed the finales of the ZSL Campaign Mutations that are Survival events. A Tank now spawns after every 60 seconds to speed up the finales.

- Made a change to Gun Game in Survivor Vs Survivor, if a player dies from self-damage they will now lose a point and go back to their previous weapon.

- Fixed a minor issue in Wave, if you hire Zoey the developer console will no longer display error messages when she kills infected.

- Added "United We Stand Realism", same as United We Stand Co-op except with Realism rules enabled.

- Updated all United We Stand modes:

(United We Stand): Changed some settings for Survival. It will now begin easier and become harder over time as more infected will appear, rather than starting off hard.
Fixed the L4D1 survivors not being given their proper items or revive status from the previous map, when the current map restarts.
Added the current clip of the L4D1 survivors pistols across map transitions, this way they're not always full in the next map. And checks if they're dual wielding them.
Added additional talker responses for Zoey. Her responses should now be complete. Also added some responses for the other survivors.
Added in "PlayerFriendlyFire" responses for the L4D1 bots when they take friendly fire damage. For some reason they would never voice those lines before.

- Updated "Witch Hunt", removed the random chance for the Witch to sit or wander.

The changes include the following:

- (VSLib) Updated with version 4.0 of VSLib. If you use my Admin System mod you'll have to download the latest update to ensure Mutations function properly.

- Made some changes to the Custom Mutations flyout menus. The menus should also support being navigated via a controller.

- Added VIP Escort Mutations, in these modes you have to prevent the VIP from dying. Thanks to "loyalists" and "Rex The Impaler" for the VIP's model.

- Added "Witchcraft", this mode contains only Witches that attack a random survivor upon spawn.

- Updated "Wave", added in the ability to hire the L4D1 survivors to assist you on L4D2 survivor maps only. This is a test and may be removed depending on feedback.

- Updated "United We Stand" and "United We Stand Co-op", made the L4D1 survivors regular bots by switching their team. Zoey is added as a fake bot due to her crashing.

Known Issues: Zoey's name will change to "Survivor" when defibbed or rescued from a closet. And her talker responses are incomplete.

Note 1: The L4D1 survivors should work for everyone without crashes. If for some reason the game does crash, it may depend on what your operating system is.
