Hello,
Well I was just looking over everything in the database and reminiscing back when I was actively working on things and saw that I had left the base iron weapons synth recipes completely broken and messed up because it used to be low on my priority list of things to fix.
So I fixed it... and I also made sure every monster / boss had a loot table and updated chapter 2 monsters to have drops relevant to the iron synth recipes
Found a bug in the first village, no longer to jump over the garden guard and or his triggers in franks garden
If there's anything else I find that needs fixed or you guys come across something that needs fixed let me know, I think you're able to get all the iron recipe books in chapter 2 currently but if you're not able to I will add them in.
