Server appears twice in XonStats
PsyX Duel (Latvia) appears twice in XonStats: http://stats.xonotic.org/search?fs=&server_name=latvia
New games are registered under the newer server ID (8141).
The server ID file (key_0.d0si.duel) is still the same, its MD5 checksum didn't change. The server wasn't rebooted before the Stats ID change.
The IP is different.
Indeed, the IP is not the same... Server 7409 has an IPv4, and the newer 8141 server has an IPv6. However, servers that have both IPv4 and IPv6 normally appear only once in XonStats.
And there is something weird: the IPv4 for server 7409 is not even the right one. The right address is 126.96.36.199:26000, but on XonStats it appears as 188.8.131.52:26000.
