Yesterday I decided to change the email for the newsletter for PPCG. However, not long after I had validated my email, the following had flooded my reputation inbox:

Now, note that I have been on Stack Overflow for three years and have earned all of these badges before.

Also, for some reason, it says I earned +3 rep in total yesterday, despite the fact that, in reality, I lost around 10.

Can anyone explain what on earth happened?

  • It isn't the first oddity with badge notifications: meta.stackexchange.com/questions/283748/…

  • @rene not related. This one here is result of account merge, in which case all the badges are re-calculated in the merge target. The bug is the merge, and only a dev can look into it though.

  • @ShadowWizard yeah, I saw the differences, wasn't sure about the cause so that is why I brought it up.

  • @rene yeah... the merge is buggy in many aspects, always was, e.g. in the OP network profile, SO appears with 0 questions and 0 answers, even though they do have posts.

That is result of account merge.

This old account of yours has been merged into your current account.

When accounts are merged, all the badges are "re-calculated", and those you deserve are awarded again, and that is what you saw. This is confirmed by animuson in this comment:

Account merges can reset all of your badges (which causes them to all be re-awarded)

  • @Beta no problem, so I take it that the merge was not accidental? (In such case I'll remove the last paragraph.)

  • Well I can't see which account was merged with mine so I have no idea

  • @Beta you can still see it in Google Cache.
