While building my own route, I somehow managed to eliminate some assets that I created. I think they were signs and the like. Iin CM, I am getting warning of missing dependencies. I have already "deleted missing assets" in surveyor. These assets still show up in the kuid table and in CM as "missing depedencies." Can I simply delete them from the config file? Or how do I get rid of them, since I don't even know what they were?
