This question already has an answer here:
I just instantly lost 211 rep on MSO.
A few hours ago I had 1,060, now 849, a 211 decrease.
I don't think I ever received enough votes on one question or answer to lose that much by a single question delete (or whatever).
My profile shows:
+10 - 7 hours ago - upvote - Notify myself with message and (optionally) a future point in time
-1 - 1 hour ago - downvoted - What questions should NOT be asked on Meta?
Where did it go? Is there somewhere else it could show why it was decreased that I am not aware of?
Ticked the box as Bart suggested, was indeed:
-220 - 1 hour ago - removed - Please, delete this post
