fix emptying carried containers

changelog.txt

@@ -46,6 +46,7 @@ Template for new versions:
 - `confirm`: properly detect clicks on the remove zone button even when the unit selection screen is also open (e.g. the vanilla assign animal to pasture panel)
 - `quickfort`: if a blueprint specifies an up/down stair, but the tile the blueprint is applied to cannot make an up stair (e.g. it has already been dug out), still designate a down stair if possible
 - `suspendmanager`: correctly handle building collisions with smoothing designations when the building is on the edge of the map
+- `empty-bin`: now correctly sends ammunition in carried quivers to the tile underneath the unit instead of teleporting them to an invalid (or possibly just far away) location
 
 ## Misc Improvements
 - `gui/control-panel`: reduce frequency for `warn-stranded` check to once every 2 days
