It's because you categorized it as *smbase-printing not
*smbase-override. Because it wasn't marked as an override, MC sees you
as having "stolen" that method (ie, maybe you control both packages and
were moving it from one to the other). So when it then disappears from
SMBase, it gets removed from the image. If it were marked as an
override and then disappeared, it would get reverted back to the
What you should do is change it to *smbase-override now, and then
you'll be relatively safe to remove it in the next version.
