The same happens for most (released) games I play. For instance, Dodo, Neutreeko and Silo give the same “-” while Bobail always say “1” no matter what.

Could you expand on the relevance this specific datum may have for this specific game?

Well, thanks for your reply and for actually raising the point.

I looked a little more at the matter and it happens to be there a file supplied by BGA with the statistics to store for a table (either for each individual player ad/or for the table as a whole). By default, this file creates a line for the number of turns but, apparently, many coders do not bother to supply any info for it once the table is over nor to modify the BGA supplied file.

I see 2 possibilities:

1) simply remove this stat;
2) supply data for the stat at table end, which requires collecting the data themselves during the game.

As it does not seem to me this datum to be particularly important (at least for this game) I inclined toward 1). Any STRONG preference?

I have fixed it in the dev version following solution 1) as described above (remove the stat).

As it is a rather minor glitch, I'm not pushing a new version just for it; it will be part of the next larger update.

Fixed.
