You have an apartment system. In this system, it has a mobile elevator that takes you to the player's AP.
In this apartment system, the rooms are basically infinite, as every player who registers an account will get one.
Surely you would say, just load the apartment of the player who logs into the server. But no, because the person who doesn't own that AP can also access it.
So I ask... Is it feasible to keep all the AP's loaded all at once and keep the information in the variables or load the information when the person accesses the elevator/spawn on the AP?
