The Steelworks mission (the first steel powered flight mission) has at least three typos.
on the left, It should say "Now that you have", not the you.
On the right, it should say "Pour molten seared stone over the "Materials and You" book".
As an aside note, when was the last time the early quest rewards were balanced? in the set of the quests you can finish in the first ten minutes, you get two pickaxes, one of which doesn't have the xp counter. You also get a non-TiCon stone axe bane of arthropods V, which seems just plain weird, as well as being a little redundant if you pick the axe over the pan in the earlier quest.
I kinda think it's against the spirit of TiCon to just hand the player the fully-made tools, don't you think replacing the tool rewards with Tier 2 tool rods makes more sense?
