What to do next is something no one's discovered yet. After praying at all 3, your journal hint tells you its time to rest (as the voice said). But after praying at all 3 and going to act 3 you get "you never did figure out what was with those voices"
wish people would stop assuming its a bug when theres zero evidence of that, probably just a super cryptic quest. we as the community can have a lot of fun trying things out and figuring out whats going on. same with the dog mentioning the memorial smelling like void fish.
Well to be fair there is a lot of broken quests and stuff, so it's not too far fetched to assume it's bugged. And still no communication from Larian on topic of quests that are actually confirmed bugged is disappointing.
