Alva incursion deleted

Okay so I'm pretty sure this is what happened :

1- complete the 12 in-map incursions
2- forget to talk to Alva
3- open a new map

expected result : no new incursion in the map until I get to talk to Alva, in order to spawn the temple or take the itemized incursion

what happens instead : incursions spawn in map, Alva gets reseted, the previously completed incursion gets deleted
