I start with an event with no graphic, then a separate event changes that graphic to the character I want (via Change Image in Set Movement Route) and then the event moves. I'll cycle through the Plugins and see if one of them is causing it to bug out then I'll edit this post. So far disabling all of plugins did not change anything.
EDIT: I've discovered that this only happens when I use Change Image in Set Movement Route. It does not cause the mid-walk pose when the event in question starts out with a graphic. And strangely enough, when I set the graphic in the event, then set it to none and THEN do the Change Image command...it actually works.
