Hey, I just updated to the latest Glyphs version 2.6.5 (1292) today and started getting these errors on export:
Something went wrong with the Remove Overlap filter in glyph: Adieresis
It’s a new glyph each time, but seems to only be uppercase compound glyphs.
I followed advice in old, but similar posts; I compiled and updated features, but no success.
I’m on MacOS Sierra 10.12.5
