The new files have the images embedded. I'm not as experienced with Affinity, so let me know if that works! Also, just a heads up, some of the fonts used are chosen because they're Adobe CC fonts, so the license won't be included with Affinity.
Ugh, I'm getting the same error (all the images are "Missing Resources"), even with the new file. Idk, it might just be Affinity. Reddit has mixed reports about whether errors should be expected. Thank you for the effort though <3
