What do you mean? This is by design: https://miqobot.com/forum/forums/topic/help-crafting/#crafting-solver
Crafting Solver works in two stages:
- Solving. At this stage Miqobot freezes completely to give more processing power to solving algorithm. The amount of time needed depends on your stats, on recipe’s difficulty, and durability. For example, an 80-durability item usually takes twice longer to solve than a 40-durability item. The time shown in the Solver box is a rough estimate, and it may vary depending on your CPU.
There is no way to stop Miqobot when she goes into frozen state, so please be patient.
- Crafting. As soon as the recipe is solved, Miqobot will be crafting non-stop just the way she does with macro rotations. At the moment, only one recipe solution can be stored in memory. If you press Stop, Miqobot will have to re-solve everything from the beginning.
The main point here is that your rotation becomes 100% optimal. It takes all factors into consideration: your stats, skill rates, condition rates, recipe difficulty. There is no predetermined logic, the solution is based on pure math.
