I just quit TextMate 2 with an untitled dirty document open, and TextMate forgot to offer to save it - it simply vanished off the screen and the work was lost.
The session state during exit is stored in ~/Library/Application Support/TextMate/Session/Info.plist and backup of open files is in the same folder. TextMate should be conservative about deleting backups, so you might still find it in that folder.
For the issue about not presenting a save dialog for an unsaved document (with a path) and furthermore not restore it after relaunch, that is not something I have heard reported before. If anyone sees similiar, it would be good to know about it.
