My guess is that the change was intentional, and that they forgot that the Zombie talent works off of a 200% Poison resistance. There was a very specific line that they had to change in the Character stats, and it fits with their intention of 'balancing' the game. I fully expect Larian to fix the Zombie talent so that it actually works again.
I don't get why the resists can't at least be capped at 100% instead of 80%. 80% just seems so unnatural.
