Ideas and suggestions.

people are already willing to pay a lot for these castles without workshops, and I'm speaking for myself, I don't like Dungeon (even though it allows you to take workshops with a speed of 9, which Flux can't boast), Dungeon is bought for the Miner, and Flux is bought by those who use Moon or Grindan, and of course, the University, and not just to roll a workshop and spend 6k, especially with a high chance of failure.
