The poison challenge counter is broken. It’s stuck at 0/1 and probably should at least say 0/500. 500 being the number or enemies the challenge says to poison. It also doesn’t move when I poison enemies. It should say 1/500 if I poison an enemy and 2/500 when I poison another enemy. 3/500 would be next. Then from there it should increment +1 per enemy poisoned. Once 500 enemies are poisoned it should complete and go to the next tier, ie poison 3000 enemies. All tiers say 0/1 though.
Same for me.
