Phototheca? is only available for Windows ... looks like a tool for hobbyists. Ok, the price is only half that of Lightroom per year, but with Lightroom you also get Photoshop. It's probably a nice tool for all former Picasa users.

Sorry - don't get me wrong ... that was not meant to sound derogatory. But is Phototheca a real Lightroom alternative? Lightroom is a bit more than a photo management tool. It's a tool for developing photos in various ways, for instance very enhanced color, exposure etc. changes and improvements.
And like the fact that Affinity's tools sharing features, it would be nice to get another tool that offers managing photos and have a focus on developing them, without the need for opening or switching to Affinity Photo.

Thanks for your fast reply, Sean.

Very good to know, and you are right - if I set the stroke to Align Center it works again. 😎

My solution was to load the design into Illustrator and reducing the nodes with the simplify function. So I got a nearly identical design, imported the design in Affinity Designer again and then I could finally export it with an outer stoke. It's a pity that I didn't found that the stroke alignment was the problem - It took me more than an hour to find a solution. 😑
