Caching Issue Between Private Code Versions of Islands

Summary

Since last night, there has been an issue with switching between playing private codes of a map that contain different content/actors. In some cases the actors from the previous code stick around when they shouldn’t, sometimes the actors that should be there are not showing.

For example, if you play a private code of a map with some Static Mesh actors in it, leave that game, load into a different version of that map without the Static Mesh actors, you will visually still see the meshes. Or vice versa. If you are in a map with no Static Mesh actors, leave, join a game with Static Mesh actors, they sometimes will not show. This issue is primarily visual, as the stale visuals do not always have collision, or the missing visuals WILL have collision.

This behavior is inconsistent, and does not happen for all players in the lobby, nor happen every time when switching between codes. However, once this problem does occur, it will continue to occur until you restart your client.

Closing your Fortnite client, and reopening it fixes the issue and seems to clear whatever caches is being left stale.

This creates extremely confusing symptoms, and concerns me as to whether players would see the changes added in an update if they havent restarted their client.
