If I have a duffel bag along with other items on my east tile and I want to move items from my inventory and the ground to the duffel bag. Is there a way to do that without wielding it.
Stand over the source duffel, wear or hold the destination duffel and either use e on the destination duffel in advanced inventory or enter in regular inventor then choose i to insert. You should see a list of everything nearby and on your person that will fit in it.
Until the PR fixing nested containers merges, don’t have the duffel inside another container when inserting things. That way lies missing items and errors. It looks like it will drop soon if it hasn’t already.
