Abyssal depth last rare to open chests MIA

https://ibb.co/4wGKMDNF

Double checked that there are no monsters left in the area.
Rare never appeared, but entering the area there was an unusual amount of magic mobs facing me. (Maybe 2-3 packs worth?)

I do use the node where map mods also affect the depths (visible in image with mods in question.)

I genuinely think theres no reason to keep those chests locked to begin with.
