There's challenges, then there's losing 136 max hp and dying from turning a fucking corner. Food poisoning needs a cap or something, this is crap.
Are you running the current hotfix (11b)? GL tweaked Rb's to reduce their deadly charges. The fix is included in the main patch releasing this week, as well. (You can read the upcoming patch notes on the homepage)
Food poisoning is part of a larger bug in buff stacking. It's getting fixed, as Apprentice has noted there is a fix available right now.
^^^ I got the first bug BEFORE CoTW. Also, i'd hate to be hit by the rutabaga in the second picture... I've never seen the murderous rutabagas (DL2) charge before. Do they even do it?
