think found the issue for the glitch above i was killing the enemies to fast guess it glitched the system. anyway found a few more glitches. first is that certain missions a character ,once corrupted, cant die the first time this happened was during the flower girl mission the scientist cant die once corrupted meaning if she gets corrupted you have to restart the mission. the second time this happened was during the parasite ambush mission ,the first time you get introduced to them, certain party members once they die become unkillable again causing you to have to reset. the third time might not be a glitch but during the tribal dance girl mission random enemies become unkillable.
another glitch i found was with the tribal mission i got all the characters back ,even those that turned against me during the previous mission, unsure if this was just added or a glitch but if it was a new feature ,which to be honest would make me happy, those that got corrupted and changed back to myside turn back to level one and uthere items get deleted.
last thing is to do with the cow girl mission unsure what the idea behind the blue cow is but well you have its spawn point set at the side of the map without a way into the pen meaning you cant do much with it.
