Welcome to the SPM forums!
Yes, this was reported in the Slitherine's forums as well (see here). Not really sure what's going on, to be honest. In any case, we're going to discontinue the manual patches soon and provide all updates via the auto-updater tool. In the meantime, please bear with us.
That's bit pity, since I am sometimes visiting rural places without own internet connection with my laptop. FTB to USB stick works for me fine in those cases.
