That’s actually a super valuable thing to know. Can you add a feature request to improve the UI to include a notification to the player? “Unable to undeploy this item. Your storage is either full, or no storage options exist that accept this item.”
This is specifically needed for the undeploy command. When harvested items sit around, it’s fairly intuitive to understand that maybe they don’t have a place to put things. I’ve sat there for whole game days wondering why someone hasn’t come to get something I’ve asked to be undeployed though, not realizing exactly why.
