The Division 2 has one expansion to date: Warlords of New York. Starting it might fast forward your character progression and lock you out of specific content/gameplay.
The game itself warns about some non-replayable side missions and trophies which might turn unreachable.
Some players talked about some blueprints which might get unavailable retrospectively... True?
Is there a list of unreachable or non-replayable achievments/content/gameplay which I might miss by prematurely starting to play the expansion? (To possibly check it off one by one.)
I currently believe that nothing will be missed, if you exhaust all story main and side missions until reaching “World Tier 1”. But is that true? (Or is there an earlier/later safe point in the game?)
Can someone confirm that all further “invaded” World Tier X missions can be (re-)launched at a later point?
