> A common pattern was that players would have mountains of skullcaps due to building their tailoring skill, but were then upset when no shop would buy 3000 skullcaps from them.
That's not really a problem with the shopkeepers. It's a gross mismatch in how difficult they made it to progress in skill versus the artificial aggregate demand for those products. If your game design requires that your players craft 3,000 of something, it's probably a good idea to think about what they're going to do with 3,000 of that especially if your players are going to expect to make a profit or if they have limited inventory.
