Q: I'm still getting that error sound when trying to pippet something I don't have in inventory (I still get ghost in the cursor), can that be removed?
A: As far as I know this is game limitation. Factorio API doesn't allow set direction of entity in cursor. So either it works like this or some other functionality will be missing. This is the related modding API request on forum: https://forums.factorio.com/viewtopic.php?f=28&t=102682&p=569639
