If the sending target of a source relay is broken and re-placed, such as when swapping out a full jar with an empty one, it seemingly forgets to send source and has to be rebound with the dominion wand. The HUD still reports as having a sending location, however.

This seems to only occur when the source jar being pulled from is empty but the relay itself has source in its internal buffer.
