Not sure if these issues are reported yet but I'll add them here anyway.
Not all quests seem to make sense, case and point "Not your average conduit" requires you to craft 32 conduits, which is fine, however it only counts each craft rather then the amount you craft. This is opposed to other quests of the same vein counting the multiple items from a single craft. I think it was the quest "Colors, so many colors" that counted most of the multi-item crafts properly thought I think one of them didn't (I think it was the orange one). This has happened for a few quests.
There is a couple of quests that's I've encountered that con't properly complete, they are "Punch tree, get wood" and "Reactionary power". Quest will complete as you would expect the first time but it never stops being purple and counting as a quest if unclaimed rewards. Further clicking on claim items and trying to turn in the quest nets you nothing, it's just an annoying bug. There might be other quests that do this but as I haven't been through the whole pack yet I'm not sure.
I would agree with boondockArtist with the whole manyullyn tools right off the bat is a bit much, I can understand because of the idea behind the first quest line is more about moving and not staying still, but I don't think you would need better then steel even if you wanted people to be able to mine everything from the start. I personally think bronze is a much better choice as it still allows for some upgrade, and gives you more of a reason to do the repair quests in the first quest line. I also agree with the whole hatchet over a lumber axe as well.
Overall though I think this is an interesting styled pack though I'm not sure what this pack wants to be. To me it just seems confused. I love the fact that it has tons of quests, though some of the quests seem to try to be a tutorial style while other ones just seem to say "you figure it out". For someone who has not used a particular mod the quests serve, more or less, to help them craft the item, however not how to use it. I will also point out here that one of the major mods I think that needs a quest line is AE2, besides looking at videos online I haven't been able to work that mod out, they changed it took much I think.
I will also mention here that there is a small "exploit" regarding the ender chests, nothing major like duping or anything just there is a way to get around the "alternate" recipes. Only noticed this one as I've crafted a million of the suckers in the past and know the recipe without looking it up, crafted 3 ender chests before trying a "white, white, white" one and got hit with the alternate recipe, which requires, in my opinion, the quest line I mentioned above.
Just thought about it, is there is in fact an AE2 quest line in there and I just haven't gotten to it yet, maybe it should be an earlier quest, maybe with it's own tab.
