hey mate
I had the same issues a while ago, and it took roughly 10 mins for it to register, its linked to the id of which you provided, just double check its the right id (open di in console and look at it).
or u can just run around the base until it shows but if all else fails, admins can take a looksie in the morning roughly 9 hours from now,
You see the 3d dimension coordinates on the right. From low to high. Please go there and let me know again.
Hint: the zone is 50 meter around your Core. If it is a large structure, it isn’t fully covered.
I tested and the zone does not match the core Cuboid. I removed the zone and gave it to you again. Please try again. Then we see if it’s a bug for Jascha or not.
The position of the OCD is according to the first placement of the core. If it was moved later (or I think even when it was done as blueprint) the coordinates might not match the new core center.
