Blueprints randomly teleport to 0,0,0

It happens randomly, with blueprints from opened levels. It doesn’t depend on blueprint type and even child actors move, sometimes without their parents
@anonymous_user_66d78fc1 : they move in editor so resetting does nothing. If grouped, some of them will move as a group (group center will be at 0,0,0)

Hi guys ,I have got excacly the same problem on the same engine version. Please Help;)
