Incursion bug (ruthless)

In ruthless with "Artefacts of the Vaal" allocated (your maps with incursions always have 4 incursions) Alva doesn't spawn in maps when last 4 incursions remain till full temple

UPDATE: more testing has shown that with "Artefacts of the Vaal" in ruthless Alva spawns, but with much lower chance. It seems that the bug is that "Artefacts of the Vaal" ignores all the "increased chance to contain Alva" nodes

This is not a bug, this is simply how Alva always had worked. The game can't track between multiple temples in a single map instance, that's why you're forced to complete the first temple before starting another one. If you take 4 incursions every map, you should have a clear rotation of 3 maps per temple.

Like I said I have 4 incursions remaining till full temple, Alva doesn't spawn in maps to finish it

Post a screenshot with the temple layout in hideout, and the overlay inside a map for the devs with a plain incursion scarab.

Likely candidates why Alva is not spawning for you: your incursion chance in your atlas tree is not 100% / did not use incursion scarab; all 12 incursions for your temple are complete and you need to take it from Alva.

I did not use scarabs - I don't have any, I had like 5 of all other missions, and can't get alva, and this is not the first time with this "Artefacts of the Vaal". Devs can look at my stats

Ok. How Alva and Incursions work is that during campaign, there is a scripted encounter and some base chance ones. After campaign, the baseline chance for Alva to appear in your maps is 6% I think (might be slightly off, somewhere between 5-8%). You can boost that with atlas tree nodes, but from what I'm deciphering you aren't there yet. So the short answer is, that you aren't supposed to get her so often and you will get her later eventually, and even make her consistent. But you do not have the necessary tools to guarantee her spawn.

Edit: You simply did not succeed in your 'dice' roll to trigger her spawn.

This is not a bug.

I have 460% increased chance for maps to contain Alva

That's impressive. There is only +104% chance on the atlas tree, plus the base chance.

Screenshots of the maps she doesn't spawn + atlas tree or video of both will go a long way. Plus a bug report number of the instances she doesn't spawn will allow GGG to generate the same instance to debug. But sounding more like user error now and we can only assist with the details you provide us.

Not sure what you mean, there's 180% increased chance just on the first 4 nodes of the tree

+96% chance allocating every Alva spawn chance node, intentionally not taking the last 8% node so it doesn't change over to "Your Maps Contain Alva".

I'm not really sure what you're seeing. The first 4 nodes on the tree are +40% chance to spawn Alva plus 40% increased chance of Alva scarabs. Unless you're multiplying them...?
