Word on the street is that this is broken, reaching out to the developers right now. As always, will post updates here. Much love.
Edit1: Made contact, figuring things out with them now!
Edit2: Patch is being worked on now. Will update with approximate date when I have it.
Edit3: There’s a patch on the way but it’s not the one that fixes the achievement. The next one after is the one that’ll fix it, since the other one was worked before they knew about this issue.
Edit4: See Docs comment below. Patch is in cert. Quick turn-around on this one.
