So In the two or three playthroughs of Lonesome Road, I notice as I enter the Divide the first time, and when the end slides pull up, I get 'Poison Removed' tags. It's not annoying or anything, but why do I get poisons removed that I never had to begin with? Is it just some Lonesome Road script or something?

It happens to me to, but I checked my effects very often when I noticed it and I wasn't poisoned at all. Could be some sort of bug with the Snakebite Tourniquet.
