The grace period notice for bounties is like this (for example):
This question had a bounty worth +50 reputation from gparyani that ended 23 hours ago.You have 10 minutes to award the bounty
The current answer(s) are out-of-date and require revision given recent changes.
If you look at the Markdown or press F7, you can see that there is no space between "ago." and "You". When will this typo be corrected?
