This is something that should probably be made a little clearer since there are so many updates. You should probably say if you are running a server or not. In the update posts for AotBT, they usually say server owners should update certain mods. I remember in one of the threads a while back there was a lot of confusion since the post said to update the config folder. I think you need to update the mods in the Mods folder and set the launcher to the newest version too. Hopefully someone smarter than me will point you (and me) to a step by step procedure.

Well thay do have witchery, but I think the two that OP mentioned are such massive and massively powerful mods they would put the pack out of balance.

I wonder if those mods fit into the vision that the guys have for this pack. I'd be surprised if they added those.

I feel your pain. Luckily I read that you ought to take a sample of your own blood and keep it in case you die.

How much RAM do you have on the server?

Yeah, stop shouting. There are tons of posts here with titles that don't describe the problem and which are all in capitals.
