I recently made a system that rotates through swords in a shop every hour. The randomness of this system is based on randomseed which is what I use to make sure it stays the same in every server. But all of these swords have a specific stock (amount that can be bought before it’s no longer available)
So how do I save the data? I want it to be quick and efficient, but I don’t want overwritten data between each server saving and loading data.
