PSA for everyone (and CC @MidnightDuel and @LootAllTheStuff)
Opened maps will stack
Maps' Item IDs stay the same as they were, it's just the "Unique" status will be removed to allow stacking.
Here's a screenshot from EdenPrime on PTS: The Deadlands II Map shown is a stack of one they previously had in inventory (copied from Live server) + one new from PTS. In other words, opened, pre-U49 maps and newly-obtained ones should all stack.

Furthermore, all zone maps must have an equal chance to drop, this heavy bias against newer zones is truly horrible. In the recent Heart's Week event, I got a lot of treasure maps, almost all of them were older maps; I got one Apocrypha map, one Solstice map, and NO West Weald map.

By the way, I got three leads in a row today in Stros M'Kai:
One from a treasure map (motif), one from normal chest (Dwarven Puzzle Box), and one from a resource node (Dwemer Star Chart). The latter was a complete surprise, since originally, it was an exceedingly rare drop, only known to come from killing wolves and beetles near Bthzark, not from a node anywhere near the Dwarven ruin.
I much preferred it when leads dropped from unique and interesting locations instead of rare Treasure Maps.
bold added by @MidnightDuel... I haven't been able to get a second Vitrified Soul Crystal lead in Solstice regardless of any rituals.

You missed out a level of RNG;
If you get a map drop in the first place,
If you get the right map
If you get a lead drop
If you get the right lead
It sometimes feels like maps drop every time but I've tried to farm just any random map before (I think for an endeavour) and it can take a while!

The subject character is an alt that I've been leveling in Antiquities and skills for a tank build. I was mostly picking-up survey maps and skyshards, along with any maps that happened to be left in the bank after the great purge.bold added by @MidnightDuel...

@MoonPile : You won't want to hear this, but I got two of those leads over the last couple days from overland treasure chests in Solstice. Different characters, but leads five and six for the account.
