BLUEPRINT ACTOR GOES TO WORLD ORIGIN IN EDITOR

My blueprint actor goes to world origin ( 0.0.0) when my project has crash . then i have to replace them one by one . it didn’t happen before, now it started. Does anyone have an answer for this problem?

I know there was a change to StaticMesh component in 5.1 where the SceneRoot now has Static/Stationary/Movable associated with it that wasn’t there before. We had to change all of our BP’s to Moveable and, prior to changing that, they were all spawning at the origin.

Not sure if this is related to your problem or not but thought I would mention it.
