Lvl 90 not getting ANY blueprint drops

I am lvl 90 now, I've done hundreds of contracts but did not get a single blueprint drop.

I found some other people reporting this issue in the past, but no solution.
Does anyone here know if there is a fix for this?
I've bought a blueprint thru trade and completed it, in the hope it will fix something but no.

I've already checked my filterblade and blueprints are on "Show".

Help?

they are rare, I have dropped only few so far.. they drop in the wild, not in contrats..

you are most likely having bad luck on blueprint drops.

I see very few blueprint drops in heists themselves. In fact, I've seen more unique contracts from heists than I have blueprints.

Most my blueprints are found in the wild, as mentioned. Allocate those Lira Arthain passives and do your map farming there; that's your best shot to self find them.

Blueprints are rare, best bet is probably to split them when you do get them.

Outside that youd probably need 15-20 maps farmed in Heist based Atlas nodes to see any decent amount of them.

I'm fully specced into Heist, I've just run about thirty maps and not a single blueprint has dropped.

I think something is messed up, I used to drop dozens of them.

UPDATE, 15 minutes later:
OK, I got three of them since I wrote this post. RNG so.

Yep RNG. I've dropped about 30 with no speccing in heist and having it blocked at times. They may of been rare when this post was made, but not particular rare currently.
