Cannot import Packed Level Actors as Reference in UE 5.1 as Outliner Input

[JanLoehr]

Hello,

Every time I try to import a Packed Level Actor as a Reference via an Outliner Input into an HDA the Houdini Session crashes. Apparently some paths it looks for aren't present on those Actors.

Adding to this, this also isn't working for regular Blueprints. Seems to only work for StaticMeshActors 🤔
