176406182 MDU6SXNzdWUxNzY0MDYxODI= 1003 Bytes being transformed to a numpy array with dtype=object in coordinates 8268008 closed 0     2 2016-09-12T15:28:21Z 2019-02-25T15:28:23Z 2019-02-25T15:28:23Z NONE      

This relates again to this code: https://gist.github.com/ceridwen/21f86231e86b72bf18fcc16fcee01548 .

``` python dataset = transform.read_games(['2016-06.json'])

dataset <xarray.Dataset> Dimensions: (event: 91, faction: 20, game: 2643, round: 7) Coordinates: * round (round) int64 0 1 2 3 4 5 6 * faction (faction) |S14 b'acolytes' b'alchemists' b'auren' ... * event (event) |S26 b'action:ACT1' b'action:ACT2' b'action:ACT3' ... * game (game) object b'005Stedda' b'006St3dda' b'00s10' b'0106' ... Data variables: player5 (game) |S17 b'Stedda' b'Muchacho' b'' b'modong' b'' b'' ... player3 (game) |S19 b'Emoht' b'Xrystofer' b'' b'runrun57' ... date (game) datetime64[ns] 2016-06-07T22:30:47 ... player1 (game) |S22 b'ocollard' b'BillyMirmidon' b'00' b'Animax' ... player2 (game) |S21 b'Mies730' b'Stedda' b'romance90' ... scoring_tiles (game, round) |S6 b'' b'SCORE9' b'SCORE4' b'SCORE2' ... player4 (game) |S20 b'Deryl' b'CarpalTunnel' b'' b'Zak_tak' b'' ... events (game, faction, event, round) float16 nan nan nan nan nan ... players_count (game) int8 5 5 2 5 3 3 4 4 4 4 4 4 5 5 5 5 5 5 5 3 3 4 2 ... ```

Notice that the dtype for the coordinate game is object, even though games is a list of bytes, that is {type(e) for e in names} evaluates to {bytes}.
