When I view What is up with the waffle fetish? in the Android app, it tells me that there is an active bounty with +100. When I click for more information on the active bounty, the app force closes because there is no active bounty on the question. Upon further inspection, Jeff's answer has been awarded the +100 bounty.
I haven't been able to reproduce on other questions outside of Meta. Unsure if that is related though.
