Checkmark Overflow

Question

I found a bug:

enter image description here

Two answers are clearly marked as correct. I hit refresh and it stays. On both of the member's profiles, the question shows up as marked correct.

Is this a bug, or just a "new feature"? Thanks for checking it out for me!

I tested myself on a question, it still flipped which one was marked for me.

Timeline also shows that both questions have been marked individually as accepted. 9 seconds apart, maybe a race condition somewhere? — Jeff Mercado

I've merged two questions that both had accepted answers before, and I've never seen this. The accepted answer on the target stays accepted. (Of course, this doesn't discount recent code changes around merging.) — Bill the Lizard

@George, if the API can tell which answers are correct, then why doesn't it automatically tick the correct answer as soon as it is posted? Or even better, why doesn't it just auto-answer with the correct answer? ... ;) — JK.

It is a bug, it happens VERY rarely.

I already have a daily job that clears this mess up and alerts us when it happens.

I do not particularly want to add a crazy amount of locking and checking just to combat the very rare cases.
