Minecraft v1.12.2
Forge v14.23.5.2821
Mighty Architect v0.2.0
Mr. Crayfish's Furniture v6.2.0

I got this while trying to load up the game.
Here's the crash log.

Blimey, this compat issue is pretty severe.
It's practically the exact same reason why the mods in the other issues crash. This should be fixed and shipped with 0.2.1 very soon.
Thank you for sharing!

Thanks!
