I have the region changer installed because I have accounts on both NA & Asia for WoT and more primarily WoWS.
The problem seems to be when I try to access the NA inventory and invites I am sending an ASIA auth token and therefor the webserver is permanently unavailable.
Could this perhaps be addressed in future updates as finding another 30gb is painful, the download time equally so on my sub 1.8mb/s link.
