Fix spell aura in Northrend and u can fly with flying mounts:
Change the line 4244 in /src/game/spell.cpp from Mangos source code in this section:
Code:
{
// not allow cast fly spells at old maps by players (all spells is self target)
if(m_caster->GetTypeId()==TYPEID_PLAYER)
{
uint32 v_map = GetVirtualMapForMapAndZone(m_caster->GetMapId(), m_caster->GetZoneId());
Change--> if( !((Player*)m_caster)->isGameMaster() && v_map != 530 && v_map != 571 && ((Player*)m_caster)->HasSpell(54197))
return SPELL_FAILED_NOT_HERE;
}
break;
}
