"There is no time like the present" can't complete

I have done more than 12 incursions tonight, on my standard character. In act 7, the causeway...
I have done a full "temple". Alva never gave me any dialogue option that look like this quest might change, advance or complete.

I CAN'T invite her to my hideout. Or anything. I'm stuck with anything related to incursions...

Edit : And doing all of that did nothing toward reputation with that master...

HELP!

I have the same issue.

I suspect it may have been caused by randomly encountering Alva in an Act 7 zone before the Causeway, and doing the incursions there, so she doesn't then appear in the Causeway

Edit: I found later on (mid the next act), and the first of the 3 Incursions finished the quest for me.

I have the same thing and I thought I was just getting annoyed at chasing what felt like endless Alva's through the story zone rather than just being able to do them at the same Alva and having some loot renewal mechanism to stop pile up interfering with pickup. (Which is, I presume, why they designed her to clone herself throughout the area instead of do multiple incursions at one spot).

The new master missions feel like arse whilst levelling honestly with Einhar seemingly hiding his beasts in the deadest corners possible so you still end up backtracking a ton, this and I'd love to comment on Delve but I've seen him once since the initial meeting in act 4 and I just hit Act 9....

It kinda feels like original master missions and GGG learned nothing about making them feel like a drag and a chore.

Same thing happened to me.
Trying to cheese it afterwards by joining another player doing this mission doesn't work either because Alva only says that she's busy.
Tried rerolling the zone for some time now to try an spawn her in that way didn't seem to work so far either.

Same thing here.

Yes, I randomly met Alva before reaching Causeway.

Facing the same issue. Encountered Alva in the Crypt before seeing her in the Causeway.

EDIT: Fixed the bug by running Causeway until Alva spawned. Once I did her incursions there it fixed it.

same bug, very annoying

Same bug, haven't found her before causeway but i suspect she might've spawned somewhere without me finding her.

Did all 3 incursions in causeway, quest stuck at "complete incursion"

Same here. Can't invite her, stuck at lvl 1.

same here - as of right now i haven't been able to spawn her again in the causeway to test if the quest can be completed that way.

[Edit] found her in the channel map - did her incursions - quest now complete.
