I fact the error is weirder than that. If I take an old Hise and export AU it works.
Then when I come back to the latest version, now I get an AU FX even if I export VST...
It's like the compiler takes only the last format...
Oh wait, I got a Projucer "permission denied" error with the last Hise here:

instead of this with an old version:
