Hello, the server number is 5029, usually with 5+ people online.
It’s very busy. Some people are tirelessly doing the Sacred Hunt, and others doing purges almost every night. However there’s no direct evidence it’s the cause of the AI blackout.
And I am pretty sure there are more NPC types affected by it, especially world bosses. In the middle of a fight, they will suddenly stop attacking, but never lose their aim on me.
