Talk:Cursed

In the toolset, there's the "Undroppable" flag (discussed here) and a "Cursed" property, specifically located as one of the options under "Additional Property" alongside the default of "Unknown". What exactly is the difference? Is it just the "Cursed" property makes it say "Cursed" in the description vs the "Undroppable" flag prevents you from actually dropping it or what?
