Mysterious XP loss

Question

I got 55555XP then suddenly my XP dropped to 55553XP. Never mind. It could be people downvoting muly best answers. This morning GAWEN gave me 5 draws, that's 25XP.
So 55553XP+25XP=55578XP, but when I check my XP, I had only 55560XP, so in total, I have mysteriously lost 20XP. How???

Answer 1

it's because of your best answer mark maybe removed or the question (in which you have the best answer) maybe removed

Answer 2

My best answers. Or when they get removed

Answer 3

I mean, you can lose XP is someone unupvotes or downvotes one of your answers.
