Failing to advance or Abandoning a base

[Dakota]

Bases loaded, tie game, 7th inning, home team at bat with 2 outs. Ball 4, winning run is walked in.

a) BR does not advance to 1st, but enters dugout.

b) R1 does not advance to home, but enters dugout.

Do you call either runner out?
Are either of these appeal plays?
Is there a difference between a) and b)?

ASA Rules, fast pitch please.
