Bug: Rift Incursion ending takes priority over providing rewards

So I had just beaten a T2 rift incursion, and was about to get the gems for beating it, when the rift incursions ended. The boss was already dead and the gem bubble about to burst, but no reward was provided as rift closing cancels all rift occurrences.

Please fix so it finishes providing rewards rather than just ending spontaneously at the timers end.
