ProjectPointToNavigation is no longer working

I am about to give up on UE4’s navigation and I can’t get an answer for this (besides that other people had similar issues). This is my setup:

It used to work fine in 4.19.. No longer works in 4.22.

I noticed if I crank up query extent to something ridiculously high on XY, like 5000,5000,100 (my default is 28,28,100), I start getting Projected Location output (which is by ~1000 units off the trace hit location).

Any idea what I am doing wrong here? Collisions are working, navmesh is there, I should be getting location returned, but I only get it returned here and there (and none for the most part in the top room).

Well, I guess I “fixed” my ProjectPointToNavigation issues by deleting all of the nav bound volumes and Recast, rebuilding, closing UE4, reloading project and adding nav volumes back (one in the Persistent level and the rest in the respective streaming levels).
