Unending Nightmare Keystone dropping obscene amounts of cluster Jewels

Just as the title says, ever since allocating Unending Nightmare Keystone I have been dropping a lot of cluster jewels. Most of them drop whenever rewards upgrade. I average 10+ cluster jewels per map and sometimes I can drop 20 of them in just one map.

I tested on 2 characters and it was the same, so not tied to a specific item. I also have most of the delirium Notables allocated, excluding only The Singular Entity (fog dissipates slower) and Screaming Whispers (more splinters). This also was not related to having delirium bosses in a map. Map rarity / quantity did not matter either as it was happening on magic maps. Only pack-size would affect things due to more monsters and thus more delirium rewards.

I tested delirium while deallocating the node and cluster jewel drop was reduced to 1-3 per map, so the usual, at least to me.

I have literally open map with delirium for the first time on my random T16 wandering path mode map and I don't even have delirium in map LMAO.
Did they disabled delirium on map device for the first time ? It was free activation, now it says it's 10c. Nice scam GGG <3
