The drops can occur even if you've been in an area for a while.  Borderlands is
a heavily streamed game so new textures/shaders can cause a hiccup.  We're
looking at ways to smooth this out.

That fits with what I expected and matches what I said above.

I don't know of any command that can assist, sorry.  Most of the commands are
disabled in release builds.
