So why didn’t it just replace the so called corrupt file rather than replacing 26 Gb of data? People are perpetuating the theory that the updater is sophisticated enough to detect tiny changes in maybe one file but its apparently not capable of replacing just that one file. Seems at best clumsy to me and at worst positively idiotic.
I think the update process for FS is unreliable and at random decides to re-install an update, I doubt if there is any clever process to it. The sim is buggy and there is no reason to assume the updater is any different
