What is the horse archer bug

Could somebody please tell me what the horse archer bug is. I've seen it in many threads but I have no idea what it is

Hi - it was introduced in patch 1.2, possibly as an unexpected result of the fix to friendly fire. Basically, it means that horse archers can nolonger fire while on the move, which drastically limits their effectiveness. There is a simple fix for this (which also works on chariots, but not elephants).

Hrvojej was kind enough to post this in a thread in the Ludus Magna forum:

\Data\export_descr_unit.txt file

Since 1.2, horse archers and related units are not able to fire on the move any more. This fix enables them to do so again, with a side-effect of changing the "ranged attack" cursor to spear-like one instead of the bow-like one. The fix for the elephant archers is still not known.

For the following unit types:

barb chariot light briton
barb horse archers scythian
barb horse archers slave
barb noble horse archers scythian
barb scythian noblewomen scythian
east persian cavalry
east cataphract archer
east horse archer
east chariot archer
egyptian bedouin
egyptian chariot archer
egyptian general's bodyguard early
rebel amazon chariots
merc horse archers
merc bedouin archers

find the line

Code:

stat_pri_attr no
change to

Code:

stat_pri_attr thrown
