What happens if you retreat on to a final frontier token?

The rules for the FF tokens talk about moving on to it. The rules for retreating do not talk about movement.

I would probably rule that you'd have to resolve the token as if you moved to it normally.

Likewise. It would be the same as retreating into a Space Mine.

I have found out that is what Correy said
