It is just me or the latest version is buggy as hell?
Can you try the cutting edge version (4.1).
Do you have any specific problem you can report that I can if it?
I’ll try to reproduce to describe it properly but it feels super random, sometime I edit on a master and it changes other master too. It got me micro heart attacks lol
I’ll try the cutting edge. Forgot about that.
Aha I ran into a reproducible crash in Glyphs 4.1 (4100) when opening a .glyphs saved by an earlier Glyphs 4.0.1 (4004) build.
It crashes while compiling the temporary font for the edit view. The stack goes through FEAIndexedCoverage indexes, FEASingleSubstitution dump, buildFeatures, and compileTempFontError, ending in an uncaught Objective-C exception.
The document had auto-generated tnum substitutions referencing source glyphs that were later marked as non-exporting (export = 0). The cached feature code was not updated, so FEAKit appears to build an invalid coverage instead of reporting or skipping those rules. Removing the stale substitutions from a copy is the current workaround.
