Disappearing loot after cut scene

Scenario:

I was on TVHM, Mayhem 4, pyre of stars, in a battle right before Tyreen/Typhon cutscene.

3 annointed: 1 militant, 1 Goon, and 1 Big Daddy (or whatever they’re called, basically a goliath), took forever to kill all three (longer than Tyreen in the end). They all solidified, fight was over, cut scene kicks in.

When it ended, that was all gone. Never got to see what loot they held, and nothing in lost loot.

Kind of a bummer.
