Playerids should be a String and not a number.

ArmaX players can play but it will generate a new Character upon every connect because the playerid is a string that contains chars e.g. "140293AX".
The current cache doesnt support this. See the regexp's in writer.pl.

According to BI playerids should be always interpreted as Strings, not numbers. See http://community.bistudio.com/wiki/getPlayerUID
