Nice work! I have a friend who has RB1 on PC, but he's only around lvl 120 or so. I'm 999 on all my characters, so this is easy for me to try, but if you are able to, could you please test my theory? For me on the PS Vita, I am unable to buy more than one Monochrome Neppy and one Dogoo Swimmer (Plutia weapons). Even with max cash stack, I cannot buy them. Only one is able to be owned at a time for me. Does this happen on the PC version as well? I eargerly await your results.
