I don't think this is a case of the puzzle being recycled, but a matter of the solution being submitted multiple times somehow, and only the first one counts; I've gotten this message multiple times, but I've always been given the points and thus dismissed this message as a system error.
I got a suggestion from "bram" that this maybe because of the more "robust" submission code: a submission
is now attempted 3 times. So possibly the first one succeeds, but somehow the acknowledgement doesn't
make it back to the browser. The 2nd one succeeds also, but now the server sends "already submitted" back
because the 1st one succeeded.
I'd like to keep these 3 attempts in there, but obviously also avoid the incorrect message..
