You want random spawn?
Can do it easily with a global variable, call it EntryPoint = 0
The default is 0.
Then on your layout, you have a check at Start of Layout.
EntryPoint = 0 => Spawn somewhere
EntryPoint = 1 => Spawn somewhere
and repeat for as many spawn points as you need.
So when you move to return to a prior layout, set the EntryPoint what you need. If you want it to be random, then set it to int(random(0,10)) or however many points you have.
