Snowie vs XG in backgames

higonefive made a very interesting post about two backgame positions where Snowie and XG rollouts disagree. It's buried deep in an old thread; I'm making a fresh post here since I think it deserves more attention.

Stick has frequently said that he doesn't trust rollouts of these kinds of positions. I'm not so skeptical of rollouts of backgames that have "crystallized" (like Robertie's problem 83) but am more skeptical of rollouts of inchoate backgames (like Robertie's problem 87).

Does anybody else have examples to share of (non-contrived) positions where rollouts on two different bots disagree sharply?
