Of course I see your point, but it does still not answer how the heck we should know if the offline installer is still needed or not.
Exactly as I've said before: you run it twice, and you see it tries to download the SAME files, over and over.
Or do you expect from every user that he knows if the files being redownloaded by FSDT Updater over and over again are the ones covered by the offline installer or not?
They don't have to know or wonder. Just follow what I've said, if the SAME files are downloaded over and over, it's because the node doesn't have the latest ones yet.
Keyword here is "OUTDATED". Why they are "outdated" to begin with ? Because the cloudflare node already had an older version, maybe coming from the Beta, or possibly even before that, so it's might serve an outdated version. Outdated requires that file already existed on cloudflare.
But new files, like the NEW liveries from the UKR operators, which were never uploaded anywhere before, cannot possibly affected by this issue, since they just didn't exist anywhere on the cloudflare network so, it's 100% sure the *first* user that downloads them, will force cloudflare to download a version from our site, because it doesn't have it, but the next user on the same node will get the cached version. The only version, so it can't be outdated.
That's why you can trust that, after running the Offline installer, and the Live Updater and you don't see anything downloaded (other than *new* files, which I'm sure are fine), you can be sure your node is ok.
