If the end game is triggered by claiming/busting a final future disk, one can still claim futures before 2 events have happened.
However, what if no more spaces are available for futures? Can one still claim them, perhaps at 5 VPs? Or perhaps no VPs are awarded but the future still happen?
I am thinking for example of the New Venus future: are the synodic comet and Venus getting destroyed (with the factory from the synodic comet moving to Venus) even if a future cannot be claimed anymore?
Same question for the Footfall future: is the synodic comet getting destroyed even if a future cannot be claimed anymore?
The above are both in a situation where the 12 year marker happens to fall in one of the 3-4 final years before the 2nd event after the game end was triggered.
In my opinion the event is happening just like the ability of Immortalists who can always try to hostile recruit regardless of loyalty despite the fact the future is unavailable (e.g. because another Colonist future has been scored by the player).
