I have backedup my necessary folders: my terrains, objects, items, particles, (There were many particles that I wanted, no duplicated ones) and textures. Once I deleted and re-downloaded FeralHeart and moved my back up folders and replaced them with the original ones I still had the same problem. I will state that I have, before deletion of the FH folder, moved my exported map and its object files into my FeralHeart+ folder.
