Bug reference 3985699794

Hi, I was doing a valdo map and it requires me to clear all strongboxes to collect the award. However, upon finishing the map (boss cleared) with 0 monsters remaining and opening all the strong boxes, no chests are spawn. I also clear everything in the mirage but still nothing spawned.

seemingly it has something to do with the mod bismuth ore deposit, just have another map failed in similar fashion

It is the bismuth ore that is bugged. Recommend avoiding valdo maps with complete ore encounters.
