In the end, I added this to the file : Config\EnderIo\SAGMillRecipes_User.xml
Code:
<recipe name="BaggingCoins" energyCost="1000">
<input>
<itemStack modID="ferretshinies" itemName="NullToken" itemMeta="0" number="50" />
</input>
<output>
<itemStack modID="ferretshinies" itemName="BlindBag" itemMeta="143" number="1" />
</output>
</recipe>
I made it just use 1000 RF as I figured bagging coins isn't that hard for a machine to do. Along with the upgraded bag -> voucher exchange I mentioned in an earlier post this made most trading quicker and easier. Mind you, only getting 1 or 2 ores in a reward crate makes trading your vouchers take a while too. By the time you trade for 200 iron crates and then unpack them all it takes a good 5 minutes. A stack crate would be awesome, crazy expensive but save SO much time.
Some general comments on the pack: I played through the pack to a point that I considered complete in a couple of days. The trading system is too cheap to beat too quickly. I got my first magic seed and made mountains of certus quartz with it (agricraft seeds at 10/10/10 with 7 sprinklers over the top are so OP), built some auto refining and submitting machines and got a fast and steady flow of coins and chits from this. I didn't need to mine anymore and quickly could redeem vouchers for anything I needed. At the start I was imagining giant factories churning out all manner of things and submitting them for lots of great rewards, but my first machine netted me so much loot that I didn't bother with anything else.
I also felt that the quests were too much "build 1 of everything from each mod". 99% of what I built I didn't use and dropped most of it into a trash can. I'm not sure how you improve on that but I grew a little tired of it after a day.
Overall, I really enjoyed the pack, for me it was just a bit short.
Thanks for great experience.
