Versions:

• Minecraft: 1.12.2
• Forge: 14.23.5.2796
• Mantle: no clue
• Tinkers Construct: none, that why I tried using this?! oO

Can it be reproduced with just Tinkers Construct, or are other mods required to reproduce the bug?
Still, this aint TiCon.
No, other mods are required.

I'm dumb ... TiCon itself was actually installed.
