This time we did some final fixes to the NPC AI data that we imported from the old system and now that we have a new nice way of defining a complex AI, we switched back to working on the bosses and combat simulation. In particular, we created a simple GM command that runs the simulation directly in the game on the currently running zone instance in real time. Which proved to be an extremely useful tool, allowing us to watch the combat and see what’s actually going on. And it allowed us to find a surprisingly big amount of bugs not only in the simulation system, but in the game in general.
