I play on Arch.mc regularly with a pixel client 1.12.2 account, but one problem i have encountered is that i cant go below y=0, making it close to impossible for me to find diamonds/loot trial chambers. Is there any client that lets me go below that? I know that with Tuff client you can go below y=0 on voidsent, so i dont know if there is a option. Any help is appreciated, even if the client completely sucks in every other aspect. Thanks a lot
