Use stuck fixes to solve one real in-game task.
Use stuck fixes when the same lake section keeps wasting time: identify the jam, clear it, and resume the normal bucket loop. You want the smallest fix that gets the water moving again.
- Fill once and note whether bucket range or fill speed is the problem.
- Use the drain return and note whether travel is the problem.
- Buy one upgrade for the bottleneck you just felt.
- Spend tokens on travel, fill, capacity, payout, or depth safety.
