Given you said this:

*don't even try using raytraced shadows they act like there is no wall at all.

*I'm troubled by the fact that raytraced shadows work fine for me.

Did you, perhaps, forget to enable raytracing? Raytraced shadows are not generated without raytracing. This is a common mistake people make. You have to enable shadows and enable raytracing in render settings, or you get no raytraced shadows.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
