Forgive me for being that guy who has to actually ask about why the canvas bags are banned. I haven't been on FTB for a while (in fact, I came back only when I heard that they had removed GregTech from Ultimate) and would like to know if the canvas bags are causing map corruption or something. Otherwise, I can't wait to get on this server and see all the awesomeness myself!
P.S.: For anyone wondering about my stance on GregTech, I was basically in a love/hate relationship with the mod. Loved the more powerful machine additions, but felt that the more expensive recipes only added to the time I needed to sink before I could finally start building epic stuff.
So yeah, I was torn about it.
*edit: I had confused the canvas bags for the alchemical bags of equivalent exchange. MAN, I'm rusty!
