Summary
Getting this error when trying to launch a session:
LogValkyrieValidation: Error: Disallowed reference to /Script/NavigationSystem.NavigationSystemV1, Referenced by:Content/Meadow_Environment_Set/Maps/MeadowsENV.umap (World), Plugin mount point:/SSMeadows.
UEFNValidation: Error: Disallowed reference to /Script/NavigationSystem.NavigationSystemV1, Referenced by:See below for asset list, Plugin mount point:/SSMeadows.
UEFNValidation: Error: /SSMeadows/Meadow_Environment_Set/Maps/MeadowsENV
This level was initially migrated from UE5 and had a few other disallowed object types that I was able to either fix manually or through running a validation fix-up. But, for whatever reason, running a validation fix-up doesn’t affect this error and I have no clue how to fix manually as I can’t seem to find any NavigationSystem info within my level/world or project settings.
I have also tried resetting any Navigation Systems settings to default within the World Settings of UE5 project and tried re-migrating but I stil get this error. I’m also not the most experienced with UE5 so I definitely could have missed something.
Any ideas what I could be doing wrong?
Edit: I was able to copy every actor from one level into a new level created within UEFN BESIDES instanced foliage and then a session will launch and I can play within my level. So, I thought the issue was with instanced foliage and deleted all of them and tried launching session within the imported UE5 levels but still receive the same error. So then I tried going through and individually deleteing meshes, landscape, and foliage until there was nothing except for Island Settings, WorldDataLayers, and WorldPartitionMiniMap and the session stil won’t launch.
