Complicated to find out why, but I know that when a friend is reanimated, he comes back with few health points, and that's a problem, so I've changed it for the next release.
( She hasn't swallowed a poison potion or a mushroom? )
Maybe the mushroom, but I was standing there rezing her so much and the effect just wouldnt go away spent at least a solid few minutes before giving up but yea just enough health to be able to finish healing potion animation so they can't get soft locked
