General questions and discussions.

I suggest making it possible to buy back artifacts that were previously sold to the merchant. The other day, I accidentally sold a ring from an elixir because I was sorting through items and equipping gloves. Also, in general, this would add a bit more variety to the gameplay. For example, you sell the artifacts you need, build a Guildhall, then, thanks to this Guildhall, you take a Utopia, and then you buy back your artifacts...
