PBW SEV: Can you use the Non-Simultaneous Turns?

[Romulus68]

These simultaneous bugs are wearing us out (failed orders) and I was curious if the other version works? works better?

Not sure what the exact name is called, but where the game process the turns like hotseat by each Empire going in turn.

Questions on that:
1. Does the turn order vary each turn?
2. Is it a random variation if it does?
3. Or does it rotate the Empire sequence? if at all.
