We apologize, but we don’t see the bug.
(14:40:23) Hitting Confirm button. :3
(14:49:29) Solver DONE: 538876.463735178 ms
The difference between timestamps is 9 min 6 sec.
Reported solving time is 538,876 ms ≈ 539 sec = 8 min 59 sec.
The mismatch of 7 seconds is the amount of time it took Miqobot to hit Confirm in the crafting log, wait for synthesis window to appear on the screen, and initiate the solving algorithm.
On a side note, please note that Crafting Solver needs only a few seconds on anything below 70*** and 1-2 minutes on 70**** recipes.
If you select any option that brings the computation time above 2 minutes, you increase the average HQ rate by 1-2% at best.
