If you assign both snippets and chunks to the same category using XPDO_TRANSPORT_RELATED_OBJECTS, when you run uninstall, it tries to remove the category twice and the second attempt throws up an error in the console.
It’s a trivial problem with no consequences that I can see, but I thought I’d mention it in case it has any implications for updating or reinstalling.
BTW, It would be nice if you could create a category in the build, then easily assign objects to it. The related objects route is pretty cumbersome.
