I found that BOB 5.2.6 snapshots don't work correctly in games with more than 8 players.
I fixed the display of wrong color character by changing in the function redrawArmies the line
var colorArray = "nrgbypcosuemvadfhijklqtwxyz",colourCode = isColourCodeOn(),i,country, quantity, base;
but I didn't found the correct color codes to add to var col0 and var col1.
