RG Live WotLK 3.3.5a

The events for the quest Scare the Guano Out of Them!, which are played after the played used the item are a bit wrong.
First the required Object Darkclaw Guano spawns at the players position but it should spawn at the position, where die firecrackers are.
Second: Some of the Darkclaw Bats are too high, so that the doesn't start. The Firecrackers appear, but not the guano nor does the bat comes down to the player.
