Topic Repair tool for SEA version ignores region.
The lag time between patches hitting NA and SEA this time round has caused a bug to manifest in the Repair tool.
As there is now a different patch on the two servers, trying to repair a 1.4.2 version SEA client will not work at the moment as the patch server used is enUS.patch.battle.net regardless of the last used region. Redirecting enUS.patch.battle.net to enSG.patch.battle.net allows the repair tool to function as normal.
This is obviously not high-priority as it would only cause problems when the patch level drifts between the servers (which will hopefully not be a common occurrence!) However, the Repair tool should be fixed to respect the correct patch server selected by the user.
