Looting 2 Gems from the same Room in Heist

I was able to take 2 gems from the same Room in Unusual Gems Heist. When I double clicked on the case with the first one and it dropped, my Alret Level didn't change. So I tried to double click on another case and only then did my Alert Level got to 100% and other cases closed.

It was Repository Heist, third room on my RF Inquisitor. Frankfurt (EU) Realm, around 12:20. Gems in questions are: Divergent Righteous Fire and Anomalous Arrogance Support.

Bug reference number: 2.064.328.939

Issue solved, I had 4% chance not to Activate Lockdown in Grand Heist, on rogue gear and didn't notice.
