Gone for me as well.

i am having the same issue. fallout 1 is missing from the library. 2 and tactics still there

The same for me, also account notification shows 1 new notification for my library, even though nothing has been updated and I haven't bought anything recently.

Both Fallout 2 and Tactics are still present in my library.

For now, only Fo1 is missing...And i have it from the promo before that ugly XMas.

Same here. Hiding/unhiding works occasionally, but not permanent. I also have a blank space lower down the shelves, and I'll look up what that game is supposed to be later, but clicking the space does nothing - doesn't expand the details/download links area like in other games.

My copy of Fallout 1 keeps appearing and disappearing... I've been missing it roughly a week ago, but it returned to my shelf shortly after. But it's gone again right now.
I wouldn't be too concerned though. Maybe it's just some temporary server glitch. If GOG is telling me "You buy it - it's yours", then I would trust them on that!

The same thing happened to me. :(

Same here :(

It's back to its original place, the first game on the first shelf. No wonder i missed it instantly.

my copy has returned as well, from werever it was hidden.

All 3 Fallouts (1,2 and tatics) are missing in my account. What happened to them?

This is GOGs response:

We currently have some kind of a bug that makes Fallout invisible periodically, on some accounts. Unfortunately we were unable to find the cause of the issue yet, but our website team works hard to find and fix it. I can assure you that the game is not permanently missing or removed from your account - this issue only affects displaying of this particular game. Also, seems like it affects only Fallout, and not a single game more.
I apologise for any inconvenience this might cause, and assure you that we will see this matter resolved as soon as we can.

But I know the real reason the games are missing.
ManBearPig ! this problem is much bigger than people suspect and I am just trying to spread ManBearPig awareness.

I am super cereal about this.

Restored for me.

Mine's still missing...

I have done a refresh almost every day hoping to get the Fallout games to show up and for the first time in I don't know how long all three just showed up in my list of games.

I will now download all three to keep as backup copy just in case the games disappear again.
I wonder if I got lucky or did the problem get fixed?

P.S. all three are showing on Galaxy also. :D
