Pretty simple bug description: The Character: Face Direction script has its left and right axis reversed.
Every character who used to be facing Right in my game is now facing Left, while the action is still set to Right. And setting it to Left flips them to the Right side
Same happens with the Character: Animate action. An animationclip with _L animates to the right, _R to the left.

PM me the characters in question, if you can.
