I tried editing it but the run, save, test, and update buttons just go to a blank page now. When I was able to test it all the other pieces seemed to work correctly.
EDIT
I still had the tab open where I was making the preset and I was able to edit it from there somehow and I think I fixed the problem. I still don't understand why, but I had to add a check to make sure the king wasn't jumping to his own starting square.
But I'm still unable to make any changes using "&submit=Edit"
I think I solved that too actually. It was something about the piece set being unselected somehow so I had to change the set group and change it back and select the right piece set again and it works.

It seems like a similar problem to this other preset I made where I'm unable to edit anything https://www.chessvariants.com/play/pbm/play.php?game=Decimate&settings=test
