All Dead Orbit, Future War Cult, and New Monarchy Tokens still in players' inventories will be reset in between Faction Rally events. It is recommended that players use these tokens with their respective faction vendor before the end of Victory Week every Faction Rally.

If it was before reset there is an issue where creating a new character has been removing tokens.
[quote] Faction Rally Tokens: We have identified an issue where Faction Rally tokens are removed when players create new characters within Destiny 2. We are seeking to resolve this issue prior to the first Faction Rallies event of Season 2[/quote]

But regardless of the above, you can only turn in earned tokens during a Faction Rally and victory week.
They will be removed before the next Faction Rally.
Nice to bo before my 1000 were taken!!!
Worse, maxed all factions, didnt get armour for each!! Shit drop rates need sorting, couldnt get 15 bits from 2000+ tokens!!
