Desperately looking for suggestions that may help me solve a printing issue, where after hours of printing the layers suddenly no longer interconnect. See photo of the two disconnected layers, where the loose part is turned upside-down to show what that first ‘loose’ layer looks like.

My first suspect is that after ‘ironing’ part of the last ‘good’ layer, the non-ironed surface cools off too much for the next layer to ’stick’. But then, if this IS the actual cause, I wonder:
- why is ironing being allowed for non-bottom and non-top surfaces?
- why does this happen after ironing the first layer?
- what could I do about it
That said, maybe I should rethink for an entirely other cause for this to happen.
Any help or suggestion towards resolving this is highly appreciated.
