Hello,
Thank you for the detailed report and for taking the time to isolate the cause — that’s very helpful.
At the moment, I’m quite busy dealing with some personal matters, but I plan to investigate this issue more thoroughly in the coming weeks.
From what you described, the high number of NPCs combined with the number of simultaneous dungeons might be contributing to the problem. I recommend trying to reduce both the total NPC count and the number of active dungeon events to see if that improves performance in the meantime.
I’ll look into this more deeply as soon as I can.
Best regards,
