I´m playing atm 10 and put curios 1.21.1 latest update and got "/curios add" comand to work but when I´m trying to use the slots I´ve added and it wont work. The relic/artifact wont stay in the slot. When I´m reseting curio back to original it works but as soon I add more than 3 feet or hands its just bugs out complitly. In previous atm pack like 9 and 7 it worked like a charm but now I dont understand.

I want to have the option to use more than 2 hands and 2 feets slots but it wont let me

Look into it and come back with results pls thx. Dont know how to explain it more

I'm having the same problem, I'm using Curios API 9.2.2+1.21.1 in the TNP Limitless 8 modpack.

Same problem here, wish this could be fixed as it is SO annoying. I can't downgrade because Cataclysm throws a fit over the Curios version.
