When you update the offline installer, would it be possible to also include any object models or textures or new operators updates?
No, because the Live Updater works. First, when we add files and textures for new operators, it's not possible having versioning issues due to server replication, because...it's a new file, it was never there in the first place, so you couldn't possibly get outdated files of a file that never existed before on the cloudfare network.
And, it would make the offline installer grow unnecessarily larger and larger, eventually reaching the same size as a full installer, since in a few years we might updated everything, which would defy the purpose of having a Live Update that only downloads what it's required to download.
In fact, sooner or later the Offline installer will likely be retired, since the only reason of possibly getting outdated files, is that Cloudflare couldn't keep up with replicating more than 30.000 files on their network after the initial release, it took several weeks for their network of servers to catch up, but nobody is really seem to have issues lately, when we only update a few files at a time.
That's the one and only reason why an Offline installer was required.
As for other updaters which you in your usual Umberto way dumb down, I very rarely had any version issues and I'm a high consumer who's been in this hobby for 30+ years...
If you read my explanation, you should have understood that you couldn't even possibly KNOW you had "version issues" with other updaters that don't check every file, one by one, every time, for its proper hash.
