I've been working towards completing the FoMT Retro Achievements set, and the kappa jewels have just stopped appearing. I got the floor 60 and 80 ones while doing my cursed tools run, then picked up the floor 0 one later on, but I've spent hours on floor 40 and floor 120 trying to find another and it just won't appear at all. I've tried resetting the floor, I've tried staying on the same floor and changing the RNG by opening the rucksack, I've tried returning on a snowy day in case that secretly increases the rng, it feels like I've tried everything. I fear there's some obscure bug I've hit that means they'll stop appearing permanently or something. Anybody have tips for getting the kappa jewels?
