I got stuck with 5.99 nighty, looking to rollback to 5.1.9.
I read about removing the stack up and zone info by editing a copy of your .kicad_pcb file in text editor
But What exacting need to remove when it says “stack up and zone info” ? and Does it really works in case of 5.99 to 5.1.9 ?
Appreciate any help. Thank you
