I don't know if it was already answered, but I've noticed it is not possible to see the common green or red highlight above the belts so to know if it can be placed... Like when wanting to rotate a belt to know if it is placeable, I have to guess after placing it if the "new" ghost will follow it.
Hm... Not sure what you are referring to exactly (mind you, haven't played Factorio in a while), but... Most likely it is expected not to be able to see all the interactions that you would be able to see with regular ghosts - this is simply a consequence of unapproved ghosts belonging to a different force than player.
But maybe you can clarify for me with some screenshots what you mean exactly - the very least I can update the "Known Issues" section.
Also, it doesn't show the yellow/green mark of underground belts to know the overall extension.
Yeah, this is normal given how the unapproved ghosts are handled (they do not belong to player's own force). I will double-check the "Known Issues" section and update it so people are aware of it (I don't expect to be able to fix it in any meaningful way).
It's not a game breaking thing, it is just a little annoying... I will understand if it is something hardcoded into the game or it is not possible anyway to fix it. (especially after 1 year without updates...)
This mod does some crazy stuff to make things work, so there's bound to be issues. In all honesty, unless the game engine starts supporting some native way of tagging specific ghost entities as not-serviceable-by-bots, probably not much that can be done (keep track of the original Construction Planner mod too, I think the original author had some alternate ideas on how to handle unapproved ghosts - provided he continued to work on it).
Thanks in advance.
Hey, not much help, no updates, but at least you get some explanation. :)
