When I opened up the book again, in Sigil, it changed all the id attributes back to heading_id_2.
Does anyone know why this happens and how to overcome it?
I never noticed this behaviour, Sigil never
changes id's which are already there. Even if you press "Create toc from headings"
This behaviour will result in duplicate id's if you merge 2 files.
Sorry, but test it again !
