I’ve been working on an interlocking font for a while and have been frustrated with the exported results when I am working with the otf file in adobe illustrator. I am designing it with interlocking letters in mind. The only letter that is giving me issues is the F, all of the other vertical and horizontal lines line up with the others perfectly. This image is the F on top of the P without any adjustments to the forms, just some tight leading, it lines up perfectly in Glyphs mini
The two bars in the middle are shifting despite the fact that they shouldn’t be. Any help?
