Minecraft Version: 1.11
Chisels and bits version: 13.4
Forge version: 2189

So this bug found my friend Minikreuz, when he was playing on server with chisel . He showed up this bug and i recorded that. I cannot explain what happens but i hope that video will be enough.
To make those bugged bits work you need to throw them.
