Problem - Chain Pull Issue

[Enki]

Hello, one day my puller started having issues with chain pulling. It gives the following response when it looks to pull another mob when the % threshold is met.

Checking for Close Range Mobs

Added 26227 to ignore pull list.
26227|26969|26307|26303|256300|null

"DoCommand - Couldn't parse /killthis
kissassist.mac@1689 (CheckStick(int p_Flag1, int p_UseAttack__: /killthis
kissassist.mac@1144 (combat): /call CheckStick 0 1
kissassist.mac@532(CheckForCombat(int SkipCombat, string
FromWhere, int WaitTime)): /call Combat
kissassist.mac@373 (Main): /call CheckForCombat 0
MainLoop2 200

It spams stuff like this until the mob dies, upon which my puller now goes to pull again.
Here is my Pull section.

PullWith=Sonic Disturbance
PullMeleeStick=0
MaxRadius=1000
MaxZRange=100
UseWayPointZ=0
PullWait=5
PullRadiusToUse=90
PullRoleToggle=0
ChainPull=1
ChainPullHP=30
PullPause=30|0
PullLevel=0|0
PullArcWidth=0
PullTwistOn=0
PullOnReturn=0
[PullAdvanced]
PullLocsOn=0

I'm not sure if for some reason he's trying to re-pull the mob that's already in camp and adding it to ignore?
I've tried multiple locations, and I'm not sure what has triggered this to stop working to begin with.
Any advice appreciated.

To get the /killthis error. MQ2Melee has been unloaded, but UseMQ2Melee is turned on. Make sure you have the most recent version of Kiss downloaded.
