Hi! If you open the dungeondraft_map file with a text editor, you can see the asset_manifest in the header. A list of all used assets is contained there. I seem to have loaded a bunch of asset packs that were actually unused. You could try the following: mark the IDs of the asset packs and run a text search - if they’re only contained in the asset manifest but not the world, you can delete the assets safely. This way, you could also eliminate assets that are unavailable to you.
