This pops up in message log under load errors when opening UEFN. Island is still working and is able to publish. The Full error is here:
While trying to load package /Game/Effects/Niagara/Systems/NS_PlayerSwimming/NS_PlayerSwimmingInWater, a dependent package /Game/Effects/Niagara/Modules/Water/WaterBodyLocation was not available. Additional explanatory information follows:
FPackageName: Skipped package /Game/Effects/Niagara/Modules/Water/WaterBodyLocation has a valid, mounted, mount point but does not exist either on disk or in iostore. The uncooked file would be expected on disk at ‘C:/Program Files/Epic Games/Fortnite/FortniteGame/Content/Effects/Niagara/Modules/Water/WaterBodyLocation.uasset’. Perhaps it has been deleted or was not synced?
I haven’t been able to upload any island since this pop up has appeared on my end. I can still live edit in FN, but the memory calculation never loads, and when it does, I cannot upload it because it states that there was an error when loading the island. I made my own report on this a few weeks ago with no real responses.
