? is it a glitch or something has been changed?
There was at least one bug with generating a glyph made of components introduced in 1179. There’s a fix for that issue on the way.
What kind of failure are you seeing? (In case there’s something else to check/fix).
Generating ss01 accented characters doesn’t replace the base glyph with the .ss01 one
Thanks. That was the bug I also reported and will likely be fixed in the next release.
