Basically what it says on the tin. I feel like I've accidentally made a librarian settle on literally never selling enchanted books somehow, and it's probably not the greatest.
Is there a way that the mod can be more completely random so that variety and checking the market periodically for with stocks for goods to trade in and out is a good idea?

or perhaps a suggested configuration to make them not settle at all, or effectively not settle all that much? Like, would I just need to set the multiplier on the settle time to something ridiculously high? cause I'd rather not have my villagers "get stuck" (or "specialize" as you call it), cause the whole reason I put this in the pack was to not have villagers stick to any similar things long term so that any mod that throws in more trades can potentially get it's limelight as the trades cycle randomly each day.

You can increase the "global_randomness" value to make the villagers settle more slowly, with something like 1000 the trades will remain pretty much completely random even if you trade with them a billion times.
Having the villagers "forget" their specialization if they're not traded with enough is something I might add as an option in the future, but right now I'm working on another mod.

gotcha, will do. thanks.
