I don't know exactly what the numbers and stuff mean, but that does mean that it was able to get at least some target, and probably it was the random hate target you wanted.
The zone crash could possibly have been caused by the leveling part of the quest. So, I would next try to remove the quest::level line and see if you can at least get the rest of it working without the zone crashes.
If that works, then you just need to keep messing around until you can figure out how to get the level part working. It may be that you will have to use level quest object command something like this instead:
Code:
$npc->SetLevel(1, false); #it might need to be $client instead of $npc
I am not sure I have the settings for that command set properly, but I imagine that the quest object might work better for the leveling part in this situation.
