Something went wrong removing overlap

For some reason, I am getting a returning error pop up: “Something went wrong when removing overlap in glyph…”

I never got these errors, but since I updated Glyphsapp to 3.0.5 it happens all the time, also when exporting a font.
Any ideas how to fix this???

And it is always just one glyph… also very weird

Probably we need to fix this. Can you send us the file?

I’m also suddenly getting this error. Any update? Thanks!

We are still collecting edge cases to improve the algorithm. If you can send me the glyph that causes the error I should be able to fix this.
