So I've heard maybe this has been an issue before, but my character in question who is a Thief, will not always auto switch back to the default evasion / parry position. I have only noticed this happening on occasion and its only ever on my Thief. Anybody else have this happen?

Well it happens somewhat regularly. I don't use charged combat maneuvers on my regular script. I do use ambush stun and backstab. I suppose it could have something to do with either of them since my barbs script is pretty much the same except for the ambush / backstab portions.
