1125  // In the rare and unlikely (like, probably never happens) case that the side does
1126  // not have a user_team_name, but an (nebulous and non-deterministic term here)

1128  // use it.

1131  // randomizing the sides on a team for multi-player games. But the effect when it's
1132  // not fixed is an obvious mistake on the player's screen when playing a campaign
1133  // in single-player mode.
1134  //
1135  // At some level, all this is probably wrong, but it is the least breakage from the
1136  // mess I found; so deal with it, or fix it.
1137  //

1139  // out for an honest design and a thoughtful implementation, you're correct! But
