The "Where did my custom game libraries go? Where did my games added to the Steam launcher go?" junk happens all the time with steam updates, I get annoyed by it and just ended up giving up on doing anything "custom" - no arranging my games by genre, no adding other games to the Steam launcher, nada. Two times of redoing that was enough to make me decide I'd just use Fences instead and that's worked great; the launcher is still useful for games I play less frequently, but for games (and their trainers, I guess!) just having them in an organized way on my desktop is way handier than a somewhat unreliable/prone to resetting customized setup in the Steam launcher.
Steam is a BIIIIIIG bunch of code. Really, really big. Tremendous. They kinda break stuff sometimes. Remember how Offline mode totally didn't work right at all for years and they they recently finally fixed it? It's not perfect, but it's Steam, after going through a retrospective/post-mortem of what actually happened and how goofy the underlying bug was, I'm giving Valve the benefit of the doubt in the future.
If you want to read more in depth as to why, check my post here:
I know that it's scary to have the idea of having all our games kicked out from under us, or having them controlled as to how we play them in single player, but it is so, so, anti-Valve to do that, and given the really just absurd nature of this particular issue and that it affected other people too for various reasons and in various ways (including just straight up games not working), and that it was a really high priority fix... I have no malice toward them at all, and don't feel like a legitimate case can be made for them having actually done anything wrong, just screwed up pushing an update and then fixing it ASAP.
If we had something to do with getting it fixed ASAP, all's the better! It sucked when our trainers broke, it was great when the CH team (Caliber especially, I understand?) fixed it pretty much immediately, and it is the best that in the end we're back to a harmonious relationship with the people who we buy games from since for a little while, before we understood what was actually happening, it was the opposite - and kind of scary, given how many games and how much money was thought to be at stake if they HAD BEEN trying to implement some kind of new anti-cheat and ban people for it.
Really glad it turned out to be a bug and not a feature. It's just so, so "not Valve"-ish to do something like that, glad that's how it ended up after all the dust settled. Thanks to the CH team for keeping cheats going while the bug was still screwing things up!
