--- Comment #32 from Alexander Milos apmichalopoulos@outlook.com --- I can't confirm for 5.8 but as for 5.9, after an exhaustive testing session consisting of downloading a single game update of 2.63GB of data, I'm no longer able to reproduce this - i.e., the game client managed to download everything without errors, apply the update and launch the game proper. So I guess it's been fixed? Still, I'll try to report again on the next game update.
