I know that the per-site meta systems aren't allowed to have bounties. However, this meta has always been allowed to have them, at least, I thought. For example, I wanted to set a bounty on this question (which is ironically about bounties), but the button to add one doesn't appear.
Was an intentional change made here to disallow bounties or is that a bug?
EDIT: To clarify, there's no button. Here's a screenshot:
