Corrupted looking chunks - likely due to weird mod

[O2theC]

Describe the bug Forge 1.12.2 when opening my world it looks super weird in mca, best way to describe it i think is, if you made the world randomly with andesite, granite, diorite and air, sometimes random at block level and sometimes at chunk level this is only visual in mca, in game it's fine

i suspect this is due to a mod i am using https://www.curseforge.com/minecraft/mc-mods/reid

To Reproduce Steps to reproduce the behavior:

1. install RoughlyEnoughIDs on forge 1.12.2 blank profile
2. launch and generate a world
3. view world through MCA
4. See error

Expected behavior i expect mca to show the world as it is

Screenshots and other files example of wack view

Environment (please complete the following information):

• OS: KDE Neon (Ubuntu)
• Java version: JRE Zulu21.32+17-CA (build 21.0.2+13-LTS)
• Version of MCA Selector 2.5.2

Additional context since i am quite sure of the reason of the error, and that it's not directly MCAs problem, i can not expect a full solution to this, but i would like if it is possible to have some solution, even if i have to hack it together to make it work, because of how REIDS works, i think it stores it in 1.13 format but with 1.12 content, and mca expects 1.13 content with 1.13 format, i'm ok if i have to do something to convert it back to 1.12 format, i'm just not sure how, on slightly unrelated that if wanted, i can make a seperate issue for, when starting mca, it always starts in the top left corner of my left monitor (3 monitors) and i have to use keybinds to just move it around so i can work with it, makes it annoying and hard to work with it quickly,
