BioWare took the servers down to fix a few bugs. Here are the patchnotes:
Warzones
-
Fixed an issue that caused groups to be unable to queue properly.
-
Resolved an issue that was causing the Ranked Warzone Arena Leaderboards to display Character information incorrectly following a server transfer.
Personally I was hoping to see an update to the credit exploit currently roaming. We encourage you to De-list your valuable items from the GTN, and await an Official response from Bioware.
