Please vote, thanks and enjoy!

v1.5 update:
-imodbits_axe for glaive, get heavy and balanced glaives
-better lances for knights (no shield penalty, quicker speed, more damage)
-removal of throwing axes for guards to even factions' ranged capability
-short sword and byzantion helmet now available to buy
-fixed tavern refill timing, professional troops a it more common,
-changed troop names for second tier rank, less confusion

v1.5 *should* be save game compatible (you may experience an equipment bug, if so, you'll have to start a new game)

v1.75 update:
-added new zendar light cavalry mercenary units
-tweaked size and spawning time of some parties
-removed some custom items mistakenly available to buy

this, likely final, update is optional as it unfortunately is not compatible with save games from the previous versions. see the thread at the taleworlds forum for information on the new units.

v2.0
-fixed mercenaries spawning on mountain
-fixed knights/cataphracts horses having no difficult rating
-fixed light leather boots having no armor rating
-made castles have infantry rather than cavalry units
-made heavy and balanced spears available to the player
-made merchant start off with pistol instead of bow

you'll need to start a new game unfortunately to have some of the above changes take effect for this version, sorry.
