Not quite programming, but software related:
After finishing the last of our scouting input, we tried to check and make sure our information was correct. The database showed that we only had 39 forms filled in instead of 300+!
It was about 11:00 at night and we had to wake up 2 mentors because no one could remember how to do a System Restore. I said "I give up! I'm done with computers! I'm going to bed!" About 2 minutes later, I came back to the room. "OK, I'm done being done with computers. What's wrong?"
It turned out that the information was all still there and that we had it set under a filter of some sort.
