i accidentally replaced my prefab with another one. now i lost my AI. is there a way to recover it?
If you haven’t closed unity yet and you overwrote this prefab recently, you can try hitting ctrl + Z to undo changes one change at a time.
Otherwise, are you using any sort of version control?
To anyone looking this up now that found themselves in this scenario where they basically replaced the entire contents of a prefab, I found a pretty simple work-around to undoing this even if you’ve closed out of Unity and didn’t have any backups. CTRL+Z doesn’t work INSIDE Unity, but if you go to the folder where your prefab was saved on your harddrive, CTRL+Z there to undo the most recent deletes within that folder to get all of the contents of your replaced prefabs back.
