Has anybody seen a csst or cuc key gardian since 2.0?

Basically the title, me and my friends have been actively looking for corrupted sand-swept tomb and underworld crypt key guardians within zones in their level range for more than a week and haven't found anything yet, do they spawn at all? Are they extremely rare? Is it a bug?

 

idk but i got three keys from tna

 

I've found CSST guardians near Thanos.

 

I've seen CSST guardians spawn around the geyser pit area in Corkus as well as in some of the areas outside Thanos and the hive entrance.

As for CUC guardians, these seem to be extremely weird in their spawning. I'm assuming they spawn somewhere within COTL, but I've personally only seen CLS and CSST guardians spawn. My personal advice is to just explore the canyon and see if you can find a spawn point for them.

 

i've actually never seen a csst or cuc guardian in like
my life

 

Haven't seen either since 2.0. Currently looking around Air Temple and CotL for the CUC key guardian but it just won't spawn. I'll keep looking but it seems like something might be wrong with the spawn rate of those two key guardians.

EDIT: found a CUC guardian at the tool merchant south of the big wheat field where the crashed blimp is. They can spawn, but are still rare.

 

I am convinced that they’re rarer than Mama Zombles

I’ve seen like one each over the span of three years

 

i've seen quite a few csst guardians while going around corkus but those sightings were before 2.0

 

I ‘ve seen a fair bit of csst guardians post 2.0 while farming avia feathers to turn into uths to turn into tols for TNA
