I'm making my first level in the editor, and it seems like the "powerup" primitive is invisible. Consequently, when I try to use it in a pattern, it's pretty much impossible to know if you placed it correctly, and if you misplaced it, it's impossible to remove (aside from deleting the pattern entirely) because the cursor never highlights it.

Is it supposed to do that, or am I doing something wrong? I think I can see a temporary workaround (attaching a tangible child object, then removing it once everything else is finished), but either way, it's kind of annoying.
