This is a common problem between big update. Unless zore has another way to force dyna-map to update the best thing to do it go into the chunk and modify it, and spend some time there. I know it sound tedious but that's how it works, Dyna-map doesn't think the map needs updating cause nothing has happened in that area. so if you do some ground modification it might update it. How much?, not sure Zore would have to weigh in on that. Or you can run around in the area? Sometimes that works for me. Just having a player in the space pops it up. That said it sometimes takes time, especially if quite a few people are on and there is a bunch of chunks that need to be updated.
