How to miter staggered stacked walls at oblique angles?

[robertbTNH4Q]

In Revit 2020 I have a series of stacked walls (framed 2x6 over conc retaining) that are staggered vertically from each other and are connected at non-right angles (each segment turns 11.25° relative to the last). If I don't vertically stagger the walls, they connect like they typically should, as circled in green on the image. However, if there is a vertical stagger, as circled in red, I get all kinds of broken geometry instead of a simple miter joint.

The part that is infuriating is that I can't use the join wall tool to fix it. The tool tends to make the problem worse; irreversibly changing the bad join on the left to the bad join on the right. And using disallow join, then joining everything to clean it up is going to get very tedious very quickly, especially we have have to modify anything.

Building this foundation and framed wall is going to be pretty simple in real life, but for Revit... it just doesn't like it. Does anyone have suggestions or work-arounds?

Had something similar but not sure how I got it to work, perhaps setting miter join and rejoining the wall location lines? Don't really remember atm. You could always rightclick and break up the stacked wall I suppose, but preferably not I guess...

I did actually try a miter join and rejoining the wall location lines, but the results were the same. I also started with two separate walls stacked on top of each other, then switched to stacked walls when that failed. Revit appears to treat them the same.

It also appears that revit only wants to miter one wall of the stack wall and the other wall. Any other walls joining that intersection default to a butt joint, which clips most of the wall out even though there is nothing there to replace it.

Add some images and/or (part of) the file. Let's see what you're looking at exactly.

Purged 2020 file attached. Take a look at the basement floor plan and the wall joins there. Building will be built into the side of a hill; hence the vertical stagger and retaining walls. And we're only in DD, so the wall thicknesses and types are still subject to heavy modification.
