Terms and payment advice missing from my invoices

Terms and payment advice are missing from my invoices after updating also Sales Invoice and Sales Quote tenplates are missing from settings?

Sales Invoice Template and Sales Quote Template concept has been actually obsolete more than a year and it wasn’t visible to new users. I needed to remove it for good since it was conflicting with other features I was working on.

You can still have a field Terms and payment advice on invoice (or quote) by simply creating custom fields. Would that be sufficient?

Oh has it i hadn’t realised! Thats fair enough if its conflicting with other features.
I am using my own invoice template so would need to alter my template.
