Bithynian: When do Heraclian allies change from using the Later Hoplite Greek list to using the Hellenistic Greek list? The changeover isn't mentioned in the Bithynian, Later Hoplite Greek or Hellenistic Greek lists. However, it's important as some time during the period in which the changeover occurs, the Bithynians also change to getting regular generals. That is, the list might allow for irregular Bithynians with Hellenistic Greek allies, or regular Bithynians with LHG allies, or neither (if the changeover occurs in the same year as the Bithynian change).
Patrician Roman/Sub-Roman British: If you provide SRB allies for a Patrician Roman army (the Riothamus option), how is the SRB contingent chosen? Is the SRB allowed the full number of "Britannia Prima" elements (the Kn (X), the Kn (F), the Bd (O) etc) even though they're optional? A strict reading of the list rules would seem to limit Riothamus to his Bd (I/O) comitatus, the LH (I) and the Sp (I), which removes any colour available with the Riothamus option.
