I get a lot of weird red error text in my world console but it doesn't seem to do anything. This is an example:

Anyone know how to fix it? It's annoying as hell 
Also, for some reason sometimes I can't melee attack or cast spells, then after a bit the npc will die, like it's lagging, but it's not. Another thing is, when my character is swaying back and forth like he is about to attack any minute, I can run
Code:
.debug castspell 5 (Death Touch [I disabled DT for certain reasons on my server])
And it will kill the NPC without delay.
+Rep to anyone that helps with either of these problems.
