I've posted this answer and I've got a downvote since at first I quoted irrelevant part of standard, yet I've also got 2 upvotes, so with score 1 (+2/-1) I deleted my answer, edited it and when it was finally correct
I undeleted it ~> downvote was removed and I've got one more upvote.
The reputation log shows: -2, +12, +2 ~> i.e. +14 rep for answer with 3 upvotes & 0 downvotes:
In this question, someone was experiencing similar problem: Got 2 plus points from downvote but I guess it was different.
Is this bug? What I am missing here?
