Something broke, but what?

While reconfiguring a very complex design to use only one spreadsheet instead of five, I noticed that a pocket resulted in a 'multiple solids' error while that pocket does not intersect the outline of the solid I wanted the pocket in...
Stripping it down to bare essentials I saw this:

end result

which is supposed to be a flat plate with two notches in the top edge, a shallow pocket on the front and an even shallower pocket on the back to create a raised edge...

No error messages in the report view, until I remove the reverse flag on the pockets: then the 'multiple solids' error comes back.
I have absolutely no clue what went wrong, the other files do not show this weirdness.

Sketch S-basePlate has two lines on top of each other as indicated in the screenshot below, you should use the Sketcher Validation Tool to find these errors.

Great find!
I can now backtrack where I went wrong, and try to prevent it happening again.

At the risk of repeating myself: more helpful error messages would be nice...

Afterthought: even the validator was not very helpful in pinpointing or even fixing the problem...
