I encountered a puzzling chain of events on this post :
- User posted a bounty on SU for all his reputation
- I answered and was awarded the bounty
- The post was migrated to SO. The bounty was deducted from my account, but not refunded to the poster.
- The poster promptly posted a bounty for me on SO for all his reputation.
The poster apparently lost his reputation because he awarded it just as the post was being migrated, so he didn't benefit from the usual refund of reputation.
It would be nice if some moderator could refund him this lost reputation.
EDIT: The poster's reputation is now restored on SU, maybe in part thanks to this post, so target achieved.
