Let's be honest, most of us made a hop town before at least once. Everyone likes to create hop towns. It became essential for many experienced players to create hop towns as it can only give you an advantage in a long run. However there's a big issue with getting a puzzle in your hop town that you know you will eventually destroy. I'm talking about tesla, tiles, garden puzzles...The only way for you to get the puzzle back will be by creating the town on an exact same spot you destroyed your hopper long time ago.
What I'd like to suggest is to have an ability to create a town that would be marked as a hop town (for everyone) and it would not have ANY puzzles or anything farmeable including monsters. Thin of a fred town. Maybe in exchange of having puzzles and all, give the hop town some advantages such as:
- Reduced amount of settlers you need for your next town BUT you can only place the town inside the hopper town domain border
- Culture boost but maybe make the defence weaker for defensive buildings
In general, the main idea is to prevent losing quest puzzles and make hop towns an actual game mechanic.
