Faction bug
 

Killing an NPC with a main faction that's set to adjustment 0 causes zone to crash. So basically, having a "social" faction without loss (for example Fire Beetle faction in VI EQ) is impossible atm.

I noticed that too, it's why all the NPCs I added have faction hits, it's a bit silly to see "Your faction standing with Giant Rats has become worse!" but better than crashing the game..
