This question incorrectly got closed as duplicate. I voted to reopen, but rather than wait for the required numbers to pass by and agree to reopen, I flagged it and asked for it to be reopened.
Meanwhile the OP re-asked the question, and got an answer. Someone noticed this, and has voted to close it again, as it is now a duplicate (of a different question than last time). I agree, so voted to close again. Again, rather than wait for the votes on an old question, I tried to flag it so a mod could close it. But it won't let me, as I have already flagged it.
This question asks basically the same thing as I'm asking, but doesn't explain why, once a mod has dealt with the first issue, the flags can't be cleared so that you can re assign for mods attention a second time.
