After several hours of testing, I've noticed that custom icons aren't being saved for blueprints.
1/ I create a blueprint and assign one of my icons to it.
It correctly displays the chosen image.
2/ I save, and the image is still correct.
3/ When I load the blueprint, it uses an image from the vanilla library.
Yet the image meets the specifications.
Even using the Vanilla image, it doesn't work.
I tried with SirDigby's mod (SatisfactoryModdingIcons), but his icons aren't recognized either.
The documentation stated that this bug was supposed to be fixed in version 1.1.
What should I do?
