After todays patch (V2.0.15), I am now getting the same repeating Error#209 "Patch Manifest Error". Very similar to the recent one a few weeks ago. Anyone else getting the error again? And yes, I closed the client, did the repair,...
Ever since I stopped using the Launcher to Launch the game I have not been bothered by this issue.
Now I only use it on Patch days and otherwise it stays closed.
I know it is not a fix to the Launcher per say, but since you never see this error message launching directly from the EXE, it is perfectly viable workaround.
