Use javolution, create a private svn and follow acis patches/changelog. Acis is a minimalism-minded project. Dropping javolution isn't something that should be done for everyone, it was just a minimal ram total used memory improvement. If you don't about ram usage (meaning you have more than 8gb of it) I'd suggest re-adding javolution even only for your event engine and focus/spend more time on crucial points of interest suchs as bugs/features etc.
 
 
my two pennies..

{X;Y;Z;H} This is the format of the co-ordinates.
 
Z is the height.
H is the Heading(where the npc looks at) and it's from -65535 to 65535
 
To find the possition you want just go there and write /loc ingame.
