Worked for me on Monday, but yeah, ran two Tuesday night and got nothing but an empty chest at the end. No reward drops or loot from the box, just went straight to mission end countdown. Nothing at postmaster either.

Just had this happen to me doing a Legendary Wellspring as well. After killing the boss, there were small amounts of glimmer still counting down, much like when starting the second encounter, where you cannot access the rally banner. No rewards dropped, and when checking the Map director, the gold star for a pinnacle was still showing as if I never took part in the encounter. At least I may have the opportunity to run the activity again but these types of bugs are increasing.

Same here. No more red borders are dropping for several days. And yesterday I only got some glimmer.
