Alignment zones error

I opened my colleague’s file which gave me the dialogue “The alignment zones are not set correctly in all masters” and refuses to generate instances. I use 1217 and he uses 1192. What’s the issue here? I don’t think there’s anything wrong with the zones.

Also there are some files which I can no longer export due to OpenType compile error, which I can in the non-beta version.

The issue is fixed in 1218.

Thanks, both?

can you send me a file with the “OpenType compile error”?
