KernOn crashes when setting special spacing groups

[Morula Type]

Hi!

Today after setting some special spacing groups, KernOn started crashing, and now every time I open it and select the glyphs for which the spacing group was changed, it crashes again. I'm on the latest release.
Is there any way I can reset the groups and start over?

Cheers!

Thanks for the notice. Would you mind sending the file? Than I can investigate. Thanks!

Sent! Thank you for looking into this

Thanks for sending the file. This crash only occurs in very specific situations (one master autokerned from another master, from which all models are removed). I just fixed it in the code.
