Thanks a lot for a milestone of buildcraft related mod, more, some functions are reference. You refreshed it with many user oriented ideas (easy user interface, control, low-lag, chestransport,...). Balance is great and only weaked by other mods like MFR or EE3 (eg. enderperls), thats desided by mod-packers.Dont worry about discussions about open source or not. What you do, is yours, we just beneficiary!
