Error getting race letter for race-less player

I got a report from a player about my map's replays breaking their script. When I tested it with a replay of my own, I got the following error:

IndexError: string index out of range

My CPU player, the seventh player, Player 14, is considered "Neutral" for its race (set in the Player Properties). The script appears to read this as an empty string, so there's no first letter to return.

Here's the replay in question. Impossible Cyrus (87).SC2Replay.zip

Start in sc2reader/objects.py at Team.lineup, specifically the play_race indexing shown in the traceback. Reproduce the failure with the attached Impossible Cyrus (87).SC2Replay and inspect how the neutral CPU player is represented. Done means sc2printer.py can process that replay without an IndexError while preserving lineup generation for players with races.
