Gold Room in Heist Blueprints is empty

Basically, sometimes when running a Heist Blueprint, the Gold Room (the one that rewards chests with only gold) is empty, there isn't any chest inside but still requires heist rogue to open it.

Possible relevant information:

Heist Blueprint area level was between 58-68
It happened both with naturally spawned gold room (already revealed by default) and with room revealed for markers with wanako.
Character level 58-62
Heist tinkert mods:
7% chance for extra armor when opening chest
4% chance for div card when opening chest
2% chance for orb of trans -> orb of chaos
6% for items to drop identified

I just ran a Blueprint in standard with 5 regular gold rooms and 7 "harbinger" gold rooms.

All the Harbinger gold rooms were empty.


Bug reference number: 4.187.388.376

When hovering these rooms, while revealing they are still called "Harbinger".
