World Partition double actor while playing

Hi everyone,

We have been facing a bizarre issue since our update to 5.2.
Most of our actors in our level are doubled by the world partition system.
I tried to deactivate/reactivate the streaming. To rebuild the game without any success. Any idea on how to solve this?

For example, here I should only have the unloaded ones.

For more precision, the level is working properly when launched from itself in the editor (I get my 13k actors in this case). The issue only happens when the level is open through the “Open Level” node from the Main menu (And here I get 22k actors).

I now have more info:

  • I can confirm it is caused by WorldPartition.

  • It only happens when the level is loaded with a node not when you play directly in the level

  • It is not 100% of actors which are spatially loaded, some of them are properly managed by the WorldPartition and not “double”.

  • It is not related to a specific Grid (Some from de None one and some on another grid)

  • Changing the grid does not fix the issue

  • Rebuild the game does not fix the issue

  • Deactivating / Reactivating streaming does not fix the issue

Until now I did not find a way to solve it or the real origin of this issue. I also do not know if there is an impact on performances but I guess it is the case as the outliner is mentioning them as actor unloaded.
