Don't you just love it when you work on a dialogue for so long then you click the wrong button and it all just disappears before your eyes before you could save it.
The love is so real! It's just fantastic! One of the reasons why I actually right everything up on a Word document before puttting it into the dlg file.. I also do very large dlg edits/creation xD
There's an option in KT for when you extract .tgas from a modules .mdl file called "Clean Model Export directory before export starts" that will delete ALL files within a folder, I suggest having it unchecked haha!
