Very strange and concerning bug... I opened a project and a test run failed because an attribute didnt exist on an actor I havent touched in months. After investigating the actor, all of the events I had been working on in a scene from my last save were now the only events on this actor. The scene still has the identical events. The actor failed for missing an attribute in the actor's event logic that is from the original scene. Even if I had accidentally deleted all events, and copy and pasted over the scene events to this actor, the attribute would have been automatically created on the actor. The attribute was then automatically removed from the actor after closing and reopening Stencyl, but the rest of the logic has still overriden the actor's original logic.
