--- Comment #2 from Øystein Sture oysstu@gmail.com --- Update: I submitted a bug report to THQ Nordic and they have patched the Titan Quest Anniversary Edition online service, and now connects successfully. The difference in behavior between the getpeername function on WINE still differs from Windows however. Other applications may still be affected.
