I've recently replayed the mentioned scenario and noticed two minor issues.
The first one is that the Pyrrhic player is unable to attach leaders to Syracusean phalanxes (the normal ones, not the elite phalanx from Syracusae). I guess it's probably an issue with the db, and that it also affects Syracusean units in the 1st Punic War scenarios.
The other issue is that the option for recalling Ptolemy as a field commander for Epirus mentions that in exchange for Ptolemy, one of the other sons of Pyrrhos, Alexandros or Helenos, will be removed from command. But what actually happens is that both are removed.
Not a very major issue, but I wanted to briefly mention it.
