Kurast Undercity-two goblins in one Kurast Undercity Run

2024-10-25T22:00:00Z, with my seasonal softcore Sorcerer, I started the Kurast Undercity with the tribute of refinement and with no bargain on T4. The first goblin has been spawned on the first floor and the second on the second floor. After killing the boss I had three chests in total, one from the Kurast Undercity and two from the two goblins. The rewards from the Kurast Undercity chest are similar to the runs without two goblins spawning me 2.000 obducites, materials, etc. and the goblin chests were also similar to the other runs dropping me tributes and other stuff, so nothing changed from the rewards. I only focused on clearing the beacons so i didnt do anything special than on my other runs with other tributes as well. Maybe its a bug, feature or I just got extremely lucky. If anyone else experienced something similar or can give clarity if its a bug or not, please share your information.
