I was making a map, and tried to bake a navigation, at first it’s looks normal. But then, after I saved and reload the editor, the navigation is gone. Oddly enough, it has been saved, and there’s it’s file in the map’s files.
Worst, all the navigation I’ve baked also gone, at least it’s invisible, the zombie still chasing me. So there’s that.
And when I tried to bake a new one with zombies in it, both zombies and navigation disappeared. (Strangely, spawn points for zombies in the newly-fricked up nagivation doesn’t disappeared)
I’ve tried restart the computer, uninstalled it completely, no luck so far.
This also occurred with every map in the editor.
