Houdini Breaking HLOD Generation

I have a HDA generating landscape and placing assets on it. However, when trying to generate HLODs for that level, it seems like this breaks it.

It throws the error “Error: Package /HoudiniEngine/houdini_default_material was saved with a newer custom version than the current. Tag 601D1886AC644F84AA16D3DE0DEAC7D6 Name ‘ForniteMain’ PackageVersion 46 MaxExpected 44”

Does anyone know if there is any way around this? Other levels I’ve created without HDAs work fine.
