I was assigned to fix and add new features to a project, the developer before me did before he leave.

All I can say, he was in a rush!!

Was he in a rush because the manager demanded he do "just one more thing" before he left, complete with ridiculous time estimate? :) IME if you leave a programmer to their own devices they're usually clever enough to wind things down on their own before they go.

@HollowKitty well, from what I heard it was do this before you leave we need you to do it asap
