Fixed stats of Dahae Cavalry

• Removed Nomad Spearmen; they are unneeded because of the steppe spearmen
  
• Set armour of Riastrad from padded to none because they do not wear any armour!

• Fixed missing unit cards for Pontic units in the IA campaign (removed faction entry in unit_variants)
  
• Added auxiliary camp variant for Pontos in the IA campaign (if using my IA unlocker)

• Units from the auxiliary submod are now available in dk auxiliary barracks
  
• Auxiliary Scutarii and Scutarii Cavalry are no longer available for Iberian & Celtiberian factions

• Added new naval units from the naval submod update
  
• Fixed missing text for dk auxiliary buildings
  
• Fixed recruitment EP of Epirotic units, e.g. light hoplites

This update contains several improvements and fixes.

• Heroic Spearmen (British unit) rebalanced, they were weaker than chosen spearmen but twice as expensive
  
• Naval unit for caetrati sword (upgrade for iberian sword) implemented, upgrades the iberan sword ship
  
• Rank sizes fixed for all units (I hope no one is left)

• Chaonian Agema - naval units cost fixed.
  
• Fixed uniform colours for a few units removed to enable faction specific colouring.

• Included the submod Auxiliary Pack from Sebidee's Unit Roasters.
  
• Fixed wrong unit sets for many units: axemen are no longer treated as sword units, peltasts no longer a archers.
