It's back at it again. About 10-15 minutes into a buildworld, I started losing my mouse. If I hit a button on the mouse, it would come back (it was just losing the connection, as if the mouse went to sleep, or had low batteries). I did that a few times, until it finally stopped working altogether. I swapped batteries thinking this was the problem, however the batteries were pretty fresh still, but the new batts did not make a difference.
