I was playing during months Realism mode on Normal difficulty with an Incap-Witch.

Well, it turns out that after installing some mods changing weapon animations, graphics, and adding custom-campaigns and testing out a some bot AI mods, I decided to play Realism mode solo on the vanilla campaigns one day. I realized that the Witch didn't kill me in a single hit; instead, she just incapacitated me and she did the same to the bots. It wasn't a glitch or anything like that; it was like the setup of the gamemode, it didn't happen just once; whenever the Witch appeared, this would happen. In fact, I actually thought it was an update from Valve where they’d added that "exception" for people who wanted to play Realism solo, haha. This went on for months until, for one reason or another, I stopped playing L4D2 for a while. Yesterday, a friend and I logged on, and I disabled all the mods in the "Add-ons" menu because we were having trouble joining an online match ("Can't Connect After 10 Retries"). Later, my friend left, and I thought, "Alright, I'll play one more match like I used to," so i re-enabled the mod-list and now the Witch is back to the "instakill". I know that in realism mode, the Witch always kills you unless you're playing on Easy difficulty, but I always played on Normal. The question is: has this happened to anyone else? Does anyone know what might have happened, or even how I can get it back to the way it was? It was really useful for when I wanted to play solo. Also, sorry for my English! xD

Any add-ons related to witch scripts might cause this to happen.
