Is there a max for lookup rules?

I’m still running FC13. I’ve revised a large font I created that uses a lot of contextual alternates: specifically, chained context substitutions. I’ve checked everything and it seems correct within FC. No errors in validation.

But in every program I try to use it, one of the chained context substitutions is no longer working. All the other chained context substitutions (10 or so) work correctly, there’s just one that won’t work. And it has 24 rules.

Is there a maximum number of rules per lookup, perhaps? I was very careful with the order of the lookups, and it works as expected within FC.

Thanks,
Dan

No, there is no such limit.

Please be aware we have fixed several issues related to OpenType layout features, so to be sure your fonts are not affected by bugs from FontCreator 13, you should seriously consider using version 14.
