Negative One (-1) Dislikes?

[Elasmosaurus]

So I'm interested to know what the go is here. I've got negative one (-1) dislikes on one of my vids. So how does that happen? I'm not fretting or anything like that, just interested is all. Anyone got any ideas?

Maybe they changed their dislike to a like?

Could of changed their dislike to a like thats the only explanation I can see.

On the hypotesis the dislike counter is a signed 32 bit integer, your video probably so many dislikes it rolled back to -1. About (2^32)-1 dislikes, if my memory doesn't betray me.
EDIT: Or maybe it's just a system bug.
