If it’s reverting back to something you had previous then:

  • Your file is not writable so your edits aren’t saving
  • Your source control (if you are using anything) isn’t accepting your changes / is reverting (although I doubt this)
  • You’re actually editing two different files. Search your hard-drive for Button.cs to see how many files there are, then check you’re actually looking at the right one.
