It appears to download and unzip an upgrade patch, unclear if it's applied, then terminates. Relaunching does the same thing, ad nauseum. Off to see if I can find a fresh launcher download, this copy is borked. @Attenwood @Chris Took a fresh download of the OS X QA launcher as linked from the OP in this thread. It ran one self update cycle and then worked, i.e., started download game patch. However, it renames itself as SotA - Launcher WITHOUT the QA postfix. It's visually identical to the real game launcher. If intentional, this is a BAD idea. If not, it's a bug in the QA launcher.
