On the quest reward popup, for a month or so now sometimes the rightmost item's graphic fails to load, so you see a star, a coin, a gap, and then a spinny circle where some other thing (e.g. a ruby) should be. You can wait several minutes without it ever loading that last graphic, even watch the ad to double the coins and xp and come back to find the circle still spinning.
This has happened at least twice, with Zeus's last quest and with Hera's last quest.
The simplest explanation for this bug would be files missing at the server side. Network problems at my end seem unlikely, given everything else including ad-doubling worked smoothly at the exact same times.
