The following minor bugs are fixed (after confirming they're still relevant):
00654E5 <MQ101Horse> and 0008B5D1 <DBCiceroHorse> still have abilities that mimic the protecion of saddles. That's just left over padding data. However the unused abilities should be deleted from Requiem.
The horse Frost always runs to a hostile creature or NPC but never attacks. After being hit, Frost flees. Setting its confidence level to 0 fixes this and makes Frost flee for every fight.
Shadowmere has lost its ability to attack and flees combat instead of aiding the player.
The 75% poison resistance on 000C5A9F <AbChaurusFX> duplicates the 60% poison resistance on the race.
The 50% poison resistance on 02002996 <AbChaurusFlyerFX> duplicates the 60% poison resistance on the race.
