Oil Extractor not dropping at a 10% rate (Distilled Fungus Node)

Distilled Fungus node - Blight chests in your maps have 10% chance to contain an oil extractor.

Don't think this node is working as intended, I've done 20-30 blighted scarabs with this allocated (with some maps having 2 blights in it thanks to the swarm node) and an oil extractor has not dropped yet.

It is on my filter as I went into standard to check and it is working fine.

I'm having the same issue, got almost all atlas skill blight nodes. I'm running several blight encounters every day and last few days I ran more than 20 blighted maps. I opened dozens (maybe hundreds) of blight chests but I didn't see any oil extractor... seems like the atlas skill "blightspawn" isn't working....

Ps: a few weeks ago I unallocated and reallocated the Blightspawn skill node and it seemed to work again but only for a short time

Please check and fix this issue.

Atlas passives don't work in blighted maps. Uh huh.

So no oil extractors is blighted maps, only oil chests in regular maps.

Just in case folks didn't know.
