[2019] Was arsenal security room nerfed?

I ran the arsenal room about 20 raids tonight and the loot seems to be heavily nerfed or somehow I had 20 bad runs. I have both keys and typically I would see high end loot 95% of the time very rarely did I not get things like bitcoins, rolers, and statues. I'm curious if the devs nerfed it.
