Text Styles in Publisher gone rogue after latest Affinity update

[Aliforce]

Hi there, I've just updated Publisher and am on V2.5.6. Mac OS Sonoma 14.7. 

When I open documents with text styles set up, the line spacing has gone haywire. I'm including a PDF of the first few pages of a document before and after upgrade. This is seriously causing me problems as these are novels, not short documents. What is the best option, dial back to the earlier version again?

The embedded font changed to a TrueType version.
Which may have different vertical metrics.

Your before PDF document shows the font as Type-1 (which could be an actual old Type-1 font, or an OTF version of the font).

AFAIK Adobe has never released a TTF version of that font.
In the old AFF11 it is only OTF.

What type fonts and what versions do you have installed?
 

Side note: always better to set a fixed line height (leading).
Prevents issues like this when upgrading fonts, working cross-platform, etc.

Thanks for your quick reply - well you know what, I think you've got something there, how odd. I had to fiddle with my Adobe subscription today because of a dull billing issue at work which I won't bore you with, and this has also coincided with this.  I had to install my Adobe fonts again. It's Adobe Caslon Pro which is OTF when I check it in Affinity, and the error looks the same in the Publisher document so it's not simply to do with the conversion to PDF. 

Looking through this document again, the major change is only with one type style which is a paragraph style for Chapter headings with a large illustration above. The space after the text has been shortened. The main body text spacing is fine because it's snapping to the baseline grid. 

I take on board your side note: looking at the text styles the leading is set to default so I could set to a fixed height to prevent in future. 

To be honest I panicked so much with this document I haven't dared open too many others to investigate further as It's my husband's birthday and I don't think I'd be to popular if I fell down an IT rabbit hole tonight!!
