Thanks for the reply!Try using the egg number range, find the frame that the target egg lands on, then do shortest path. It'll tell say how many eggs to accept/reject.
Edit: Using the info you provided, it says you'd have to accept 165 eggs and reject 7 times to hit frame 4576.
I tried this now and it shows me the accept/reject numbers, but again when I press ''Shortest Path'' and hit ''Calculate'' the program freeze. Why is this?
I filled in details for breeding anoher Pokémon (Togedemaru) and it works.
I noticed with the previous Pokémon (Cutiefly) details I didn't get a +## on my shiny frames (see my picture in my first post). I guess that causes the freeze, but again.. why?
Tried to fill in details for different parents to see what results I get, but all of them doesnt want to show me the shortest path as mentioned before... And now also for the Togedemaru doesnt work anymore. I am super lost... Without the ''Shortest path'' option I do not know which Egg I need to refuse.
