This ticket is regarding a player issue on out official ATM3 server. It is related to Mekanism/Tinkers crash with hammers and pipes (see: #99).

I have fixed hatter being able to log in. The crash will happen if you LOOK at a mekanism pipe/cable while holding a Tinker's hammer so I just changed the "active slot" of what item is currently held
