Chisel crashes on server startup, due to running client side version of I18n.
I suspect that my changes to the Chisel config might be what causes the code to be called (Haven't look too much into it), so I have attached that too.

Yeah, enabling B:tooltipsUseBlockDescriptions on the server should fix this temporarily. I will push a fix soon, currently a lot of code is being changed due to the new mod.
