Not sure if you are (or have been) on the Emu discord, but this zone server issue has been happening to several people, which is frustrating, because I haven't seen anyone post any substantial cause for it, let alone a solution.
Even though I don't have that problem, I would love to see people take a more diligent approach to finding out what's going on, especially when something like that happens randomly to a server without any changes. I have an older code/database project that was untouched and one day, out of the blue, it had a (different) issue pop up, which hasn't been resolved yet, so I know how frustrating it can be.
