Missing Valdo-Reward

Decided on doing my first Valdo's Map, full-cleared the map and then did the Abyss.
Resulted in not getting any rewards (as I found out, there's supposed to be a chest spawning containing the reward).
I assume the spawning of the Abyss Chest overwrote the spawning of the Valdo Box, resulting in me missing out on my reward.

Attached the map itself and me on map with the reference number

Yeah, i had same issue just a different Map/Reward. Seems like Abyss is buggy again.

Must be unlucky because of Progenesis, mine was Watchers Eye.

ah ha, guess how I ended up in this thread...

Valdo Caldera map with Forbidden Flame reward, also featuring an Abyss.
