Something sounds a bit fishy here.

Next time a spoke is removed, check for right facing vs left facing spoke holes. I have troubles recognising them, but hang a spoke (or stub) from a nipple and see which direction it naturally points when leaning the wheel right or left.
3x or greater with 32 or fewer holes?
I think small rims may also be harsher on spokes. I'm hoping to build up a few deep rims soon. I'll see how that goes.
