Knowing I did not hinted my font, If I uncheck “Autohint” in export dialog, everything works. As far as I remember, the only parameter I changed wad the grid/subgrid values in font info. I have corrected paths direction, tidy up paths for every glyph in the file, still getting the error, any help?
Different start point sometimes helps, and shifting the glyph a few units. Otherwise, you can exclude it from autohinting with a Disable autohinting for glyphs parameter.
I’ve tried to shift the position or change the start point but got the same result. For the parameter, I used it already for other glyphs but the problem itself is strange to me because it was the first time I encounter it. It seems to happen after last update I think.
It’s happening to me, too, but with other glyph. As far as I can remember, I have every parameter set right, correct paths direction and tied up paths.
Just chiming in to mention it just occurred for me as well. Not sure what I did differently, but occurred after updating to the most recent version. I also tidied paths, correct path directions, etc.
