so im playing AOF5 and its sayong in order to craft the electric circuit i need the chemical rector but i need a EC to make one but need that block to make it so idk if its an issue with the modpack or just a bug

There's another way to craft an EC that doesn't require the chemical reactor. Check again in REI.

i need the thing to make the n plates there is no other way?

you dont need N nor P doped silicon plates you can just use regular silicon plates you just get half of what you would get with them

ohhhhh thank you it didnt say that i dont think could have just looked over it thank you
