Not sure why it would be null here, try

if (getActiveChar().hasAI() && getActiveChar().getAI().getIntention()...

If you got other AI issues, you have to analyze why the AI is dropped while being checked which is probably something you couldn't handle alone.

I can't understand why this happen only in Floran fort , maybe its a zone issue? with coords etc?

[Tryskell]

Nope it's about defender knownlist, aka the list of target that NPC can see. There's a problem with setting the AI intention, looks like the AI is null when it reaches that part of code.

 

Either getActiveChar() is null, or getAI() is null. One or the other reference is maybe deleted "meanwhile", aka when the code is processing, AI is normally deleted only if there is no players around the region. Normally the knownlist entity is stucked to the entity.

 

You should check exactly when it happens, if it is cyclic, if you just spawn one player nearby, if it's during event (fortress) launch, etc etc.

It happens only in Floran fortress and only by the 4 balcony Guards if i delete them then there is no error.

 

also this error i get when i try to kill the balcony "stucked" guards:

Anyway thanks for your help!

I found and fixed the issue it was a part of the code inside L2DefenderInstance.java

 

All the fortress/castle guards worked fine.... but those 4 Guard in floran "found" the issue in the code : )

Thanks again.
