Check both sides first
Know what should leave the source and where it should arrive. Capacity, restrictions, or interruption can make a transfer look complete when it is not.
Verify Grab All
The official demo update supports the interaction. Use it when there is room, then compare source and destination before closing.
Build a storage convention
Use stable categories such as immediate supplies, tools, building materials, and unknown items. Consistency reduces accidental loss.
Report persistence separately
If an item changes after travel, reload, or restart, record that transition separately from the initial transfer.
