[Logic_]

The only solution I know about this is to use CreateObject for base objects such as a land etc where the player or vehicles might spawn, the rest can be CreateDynamicObject.

The CreateObject creates an object forever and CreateDynamicObject creates a per-player object for players near that position else destroys them. Both of them use the object slot.

Hope my response helps you and I'm not wrong with the knowledge I've about objects.
