The bug happens while the character tries to walk while stunned and this message appears "[MovementManager] Think we are stuck".
I could also imagine it, it would also happen with other movement impairing effects such as roots.
If the event "MovementEvents.OnSeemStuck" is registered this will be also called.
If someone else would use this event for an own bug reporting, this would result in false-positive reports.
