The only other answer is some airplane elf came and reindexed your prop
in the middle of the night :-)


May not be as strange as it sounds.

Maybe someone needed a prop. They stole one, put it on your plane and stole
yours. That way the one reported as stolen is on your plane, which you may
never find out about. Mr prop theif winds up with yours, which never gets
reported.
