By Turn 88 (Year -251) of my Pergamon playthrough I've seized the Ionian coast, the Hellespont, Phrygia, and Galatia but the reform is still not triggering. Is it because I've refused Galatian tribute and defeated some of their armies? I didn't seize Ankyra from the Eleutheroi, but from the Seleukides. I also haven't conquered Side and Tarsos.
