Days before I designed and used an asset created with PO using a few local textures in the AppData>Colossal Order>Cities_Skylines>ProdeduralObjects>Textures path. When other city decorations were done, I saved my file and next day these assets have the "texture not loaded" error displayed on such assets. Things are not bettered when I hit the "reload" button. In this case, what should I do/check?
