        {
            _log.warning("There was an error while updating account:" + e);
        }
    }
}

After you are passing this the only thing that you have to do is create a new npc with type: L2Password.

HAVE A NICE DAY GUYS :)

he did actually

thepsolartek · April 12, 2019

As you can see in the start of this topic i ve already told that the code didnt belong to me but Sweets. The only thing i did is to make the imports correct for acis 370 and do the necessary changes where the code has error. I did that for members that didnt know how to use eclipse very well and what changes are done in acis 370.

Normally it's L2NpcInstance. Adjust to your pack - simply check another instance file, see what does it extends.

I compile with this code but when I use instance L2Password on a NPC I dont have interface in html windows
