Thank you so very much for warning us about not collecting our World Boss award until you've given the go-ahead! I was 16 minutes away from collecting when I read the "news"!
If you successfully collected it's fine. In my tests the Boss remains on your screen uncollected, so it should work fine after the fix.
i see. so it was an issue with being unable to collect the rewards, and if you were able to collect you have nothing to worry about. thanks!
