i have the latest version of both litematica and malilib (im also using optifine, optifabric, and worldedit if that matters). im on 1.17.1
im trying to make a schematic of this largish build im making but whenever i try to load it, it always goes in incorrectly. like the chunks are all swapped (video for reference)

is there any way to fix this? is it my fault?
edit: all of the chunks are loaded when i make the schematic

With Optifine installed you usually need to disable the Render Regions option in the Video settings, otherwise it will end up shuffling around the chunk renderers.
