Problem with generating ligatures

I created actiually my first ligature and follow the instruction on this tutorial:

Now my problem is that if I add the suffix .liga there will not be automatic generate sub f t by f_t.liga; into liga.
without it will generate the sub f t by f_t; in dliga like in the tutorial.
What do I’m wrong btw. what hav I to do to get it work?


Tried it in Version 2.3b (873), and it works as expected. Are you pressing the Update button in Font Info > Features?

mmh, yesterday I startet new with this font as a multiple master, before I had only one font-file, and now it works.
I don’t understand that.

Thanks for your replay.
