Physics assets within a blueprint react improperly when placed in a sublevel. This error can clearly be seen within a user's youtube video located here:
The fan asset attached to jira works as intended in persistent level, it only breaks when placed within a sublevel.
1. Download, unzip, add attached folder to contents of any project
2. Open project>Window>Levels>Level>Add New>"name">Save
3. Make sublevel current level, set streaming method to always loaded
4. Place copy of blueprint fan from added content into sublevel
5. Press PIE
Level opens, fan appears broken/disjointed.
Fan loads into level properly, interacting with fan causes it to swing. The fans pieces all interact without any noticeable breaks.
