Your dumbest mistake

[MrBehemoth]

All of these.

The most common mistake I make is usually just a simple typo, or like Mendelssohn said, referencing "Something1" instead of "Something_1" and spending hooooooours testing and debugging, trying different approaches, wondering if it's an engine bug, asking my wife, pulling out my hair, then finally isolating each block of code and narrowing it down to some stoopid, pitiful, minor typo.

Here's a non-scripting one that I can't undo:
In The Trapdoor, most of Burke's voice-over was recorded in one sitting, with another a few weeks later for some extra lines and do-overs. The first time around, I recorded it all at my normal voice pitch (with an accent) and then digitally lowered the pitch by one semi-tone. The second time around I listened to the previous recordings, to make sure the pitch and accent matched. Only I didn't listen to the original recordings, I listened to the pitch-lowered ones, copied them with my voice and then lowered them again. The result is that there are points in the game where Burke's voice suddenly drops or lifts by a semi-tone, which is quite a noticeable difference. For example in the cutscene/flashback "Whatever this treasure is I feel it calling to me. |pitchshift!| I long to feel the blah blah blah". I like to watch Let's Plays of my mods, as a learning experience, and this makes me cringe every time I hear it.
