Yea, I remember when I started crafting 16 HV solar arrays.The most painful expirience in Tekkit
128 MVSA --> 1024 LVSA --> 8192 solar pannels (81 920 refined metal, 16 384 electronic circuit, 1042 machine blocks etc.)
For this kind of things CT3 is very helpfull because you don't need to put in the table every item individually. Don't get me wrong I have nothing against crafting items like this, but for mass production it's a big no-no. I haven't tried to set up an automatic crafting system because it would take me longer to accomplish my goal.
For me CT3 was a little buggy, or at least it seemed buggy and as I sad before I have only used it for mass production. I really hope that the CT3 will be fixed and readded in the future. If not, well it was an helpfull item but nothing more. It will not be missed.
