Okay so I guess the title is misleading. Recomplex is useless I have been waiting on that mod to work as intended since 17 or more versions ago but the author seems far more focused on 1.11.2. He left 1.10.2 in a broken state. I have been trying again and again to get him to fix many many things.

the biggest things are

-Being able to import and export structures since its latest release it just breaks again and again.
-Being able to spawn structures that keep there item contents.
-Saving NBT data so I can spawn in a structure with different mods and not have issues with wether those mods keep working.

Please save me.
