EntityLink path hashes not supported by the game?

[kapuragu]

It seems like MGSV might not accept the paths hashed in EntityLink by FoxTool. For instance, the linked DataSet is supposed to link to .../cuba_common_asset.fox2 in a DecalArray's material property. You can find paths to .fox2 files in the vanilla DataSet when looking at it with a hex editor, but you can't in the repacked one.

However, when repacked, the path in EntityLink is hashed, and the DecalArray doesn't apply in-game. (The terrain the screenshot might be an unrelated issue)

The DecalArray entity with an EntityLink works fine if the entity it links to is in the archive and if an address is given (links to entities in other datasets don't seem to require one in vanilla and use 0x00000000)
