I have several issues with it:
- In my opinion, the name is quite un-informative, which also causes problems for translators. A better name could be "Requested item placeholder" or something along those lines.
- There's absolutely no ingame indication of:
- What causes it?
- How to get rid of it?
- Why does it mysteriously go away when "mined"?
- What differentiates this entity from the "missing components" warning sign (which is how it appears on the map btw).
