Spurious feature error bug


#1

I’m currently seeing a bug where the Features menu at the bottom left shows me a red exclamation mark whenever I open a specific typeface. When I compile the features, the signal goes away. But when I save and reopen the typeface, it appears again.


#2

I always thought that exclamation mark just means the features are not compiled.


#3

Why would it revert back to being uncompiled upon reopening, though? And it doesn’t happen in all my typefaces.


#4

it is supposed to compile it in opening the file. I have a look.
