Minor bug: the neurotoxin counter disappears when neurotoxin and purify cancel each other out. That is, if my oppenent plays purify (say +2), and then I bring out my dune scorpion, the blue +2 will turn into a yellow +1 (correctly). Next turn/card played, it will disappear, because they've canceled each other out (correctly). But then it won't reappear with further cards. Note that the correct poison counter is still being applied, its just an issue of the counter disappearing. And if I land another hit with dune scorpion, it will reappear with the correct number at that point. This only comes up when I score a neurotoxin hit over a purify and then my dune scorpion is either killed or otherwise incapacitated. Like I said, minor bug, but probably easily fixed.
