From Close votes shouldn't expire on bountied questions on MSE:
Remember: closing is a nomination for deletion. Saying, "Oh, no need
to involve a moderator; if close votes don't expire, I'll just sit on
my hands until the bounty is done and then close -> delete it" is
effectively saying,
"I'm fine with someone putting serious effort into answering this question out of hope for a bounty reward, because I plan to delete the
question and their answer, thus erasing both their effort and the
reputation involved."
Don't do that. Contact a moderator - if the question must be closed
or migrated, they can refund the bounty and do so immediately,
removing the question from the Featured list. The longer you wait, the
more potential for grief exists for everyone involved.
I will point out that while my close vote on the round 1 was reopened, there appears to be at least a reasonable number of people looking at closing it on round 2 (once the bounty expires).
If the question is not improved (and there doesn't seem to be any attempt by the OP to do so) to one that is answerable, once it is closed, I intend to cast a delete vote on it.
Thus, hey you guys mods: "Before someone puts in some serious effort into answering this question out of hope for a bounty, you should look at letting this question get closed so that it can get fixed to not be vague so that I don't feel the need to delete vote it once the bounty expires and it gets closed again."
