The build command is not very well optimised, nor does it work efficiently at all. I would only recommend using it for building schematics that have solid blocks and are very basic.
Baritone supports 1.12 schematics (file.schematic), new schematics (file.schem), and nbt files (file.nbt). In order to build a litematic file you’d need to convert it to a schem. This can be done with world edit (paste the schem with litematica, then copy with worldedit and save)
@6ikm okay so i tried loading a different version of minecraft. (1.12.2) and i checked my versions folder. nothing. just 1.19. 1.8.9. and aristois. i dont know what is going on but im going to factory reset my pc
@dyiing but meteor just crashes the game if you just place it in .minecraft/libraries/me/deftware/emc-f-v2/latest-1.19 how can i stop it from crashing the game.
it worked in aristos 1.18.2 free edition
Your files were outdated. MultiMC cannot automatically update the libraries. When it's updated you must delete libraries/net and libraries/me to generate the correct files.
