I have the same problem here, I know the report is from six months ago, but I has played with all the angels mods and the fix for work fine, until i begining to mange the science pack too I have no problems, all the recepes are ok, but to make the science pack 2 we need boron trioxide, for make boron trioxide we need boric acid an for make this we need Diborane plus the electrolyser. To get electrolyser science pack 2. I really love the mod.
Obs: Sorry about my english I still learne the language.
