3d models dont work after installing nu angel island zones models and after deleting the models folder and putting the og back in.

[CouthPuma653641]

Ok. Hear me out. So i installed nu angel island zone and i wanted to play with the 3d models that it has. The only problem? After i replaced them, the rings, characters and anything else from the normal game stopped working, but nu angel islands zone worked. I tried today to replace the models again with the ones from the archive on srb2.org/downloads but, when i tried, the models were still not working for some reason. If anyone can help me the thank you. (Also i put this in unmodified troubleshooting bc this happens even when no mods are loaded.)

EDIT: Ok i removed some files and put back the ogs and they work. Neat.
