Hello,

I've seen this happen 3 times so far. While completing a guildleve, the last enemy attempts to run away. If I had just hit him with my Skull Sunder, and inflicted him with the DOT from the ability, and the enemy dies, the kill can register properly (i.e 6/6 killed) but the leve doesn't complete. This has been seen with the Sylphid Swarms, Dodos, and carrions, on each of their respective leves.
