I am continually using golems. And I could have sworn that it used to be that every time a golem was used up, I would need to procure a new scheme to make another one.

Well, recently I've begun to notice that I haven't needed to replace the schemes in my library, and have continued to reuse them. This confuses me, because I seriously don't remember it being like that.

Which is it? Was there an update, or am I just remembering things wrong?

I think you're just remembering wrong, since as far as I know, it has been like that, where once the golem collapses you can just build them again.

Huh. Well, I guess it would explain why I have so many unused schemes lying around...

Don't know where I'm getting that idea at all, but thanks for the answer. 

Part of your confusion may be because it's possible to upgrade recipes by adding up to 4 additional copies to your library.

It's irrelevant for things like golems and bandages but each extra copy reduces the amount of silver required to craft something. Once you've reached the max # of copies the silver cost is cut in half.

Ok, was not aware of that. Thank you!
