Hey gang, just updated to 4.20.2 and started a build w the following error;

UATHelper: Packaging (Windows (64-bit)): LogNavigation: Error: [/Script/Engine.RecastNavMesh] found in the DefaultEngine.ini file. This class has been moved. Please rename that section to [/Script/NavigationSystem.RecastNavMesh]
PackagingResults: Error: [/Script/Engine.RecastNavMesh] found in the DefaultEngine.ini file. This class has been moved. Please rename that section to [/Script/NavigationSystem.RecastNavMesh]

What is this and how do I fix it? Thanks for any help!
I am not currently using VS.

Try clicking on the down arrow next to UE 4.20 and verifying the files if that doesn’t work you might try reinstalling

Neither worked. Any other suggestions?

It says right there in the message:

Please rename that section to [/Script/NavigationSystem.RecastNavMesh]

So just open DefaultEngine.ini (in your Config directory) in any editor and replace

[/Script/Engine.RecastNavMesh]

with:

[/Script/NavigationSystem.RecastNavMesh]

I’m getting this error but it’s already /Script/NavigationSystem.RecastNavMesh… Build 4.21…

My DefaultEngine.ini already has:

[/Script/NavigationSystem.RecastNavMesh]
CellSize=8.000000
AgentRadius=28.000000
AgentMaxStepHeight=50.326584
AgentMaxSlope=76.209518

There’s no instance of the old scripting in the text file but I’m getting the error anyway.
