Glyphs 3 finds "Remove overlap" errors that Glyphs 2 didn't complain about

Exporting the same file in Glyphs 3 as Glyphs 2 now fails with:

Something went wrong when Removing Overlap in glyph

I’m not sure what I should be looking for, as there are no overlaps that I can see. Is there any more precise information available?

Can you send me the .glyphs file?

I have the same problem, seems to happen more in files with larger charsets

I am facing the same issue.

The glyphs the errors are detected are not previewing the original overlapped contour, but rather the non-overlapped preview.

Also, it has been observed that this phenomenon can be resolved by removing the specific points or modifying the Y coordinate.

I’ll send the .glyphs file to support(at) and would be happy to review it.

Thanks in advance.

Just FYI, the problem is still present in version 3.0.1 (3033).

Can you send me your file?

I’ve re-sent it.
