Due to a unity error that kept popping up when I was backing up my files, my UI scripts disappeared, and I wasn’t able to add them since the only way they can be added is via Add Component > UI, meaning that I need to re-add all components of the code. This is frustrating because I lose any variables that I declared in the inspector.
Result of the bug. Some UI elements with the same problem disappeared completely, sucha s the reticle.
EDIT: (02/12/15)
I was able to find a fix to this problem by deleting the library folder in the project, then re-opening it so that it reimports all of the assets. Apparently it’s a metadata caused by switching computers.
