It seems like Rotation Lock messes with the Factories from Mekanism, because if you have it active and try to place a Factory it will convert into a Smelting factory of that Tier.

Infos:
Minecraft Version: 1.12.2
Quark Version: r1.6
SpongeForge : 1.12.2-2838-7.1.8

(sorry for such a long log, server been up for a while and players were on it at the same time :/)

This also happens with other Mekanism tiered items, such as the tanks.

Without SpongeForge, in singleplayer, using Quark-r1.6-179 and Forge-1.12.2-2847
