Using the AE2 auto crafting crashes the server, our setup seems fine as a default one with not much special. When requesting 64x items of something it gives me an error in the chat, but once we ask 1 item, it flat out crashes the server. we put a sign up on our base "DO NOT AUTO CRAFT" but we'd like to use it, or replace AE2 with something else if needed.
You can poke Hazzytje, SpicedSchnitzel or me if you want to go to us to see the setup or check it out. we're one team together.
