Remarks

Unknown. The person who found this was unable to disassemble Warcraft III's game.dll without a lot of trouble, and therefore had limited knowledge of it. It has been seen once, after SID_LOGONPROOF (0x54) in the NLS logon sequence.

Found at: game.dll

[Update 03/14/2016]: It was also seen during the Warcraft III 1.27a patch shortly before it went live. Here are some snapshots from a couple different bots:

UserLoser

Server responds with SID_0043 when sending a /stats request for WAR3/W3XP when the user has no stats

i.e. "/stats UserBot WAR3" returns SID_0043 with 32-bit zero value if no stats exist on that account
