that, unlike the library, the bundle download page isn't searchable
Yeah, nor personally organizable. This is a huge issue.
Viewing post in Bundle not showing up in library
the organizability or lack thereof, while an issue, isn't as bad as the fact it literally lies to you about owning the game though, which without any search on the bundle you can't even double check (except by literally comparing 750 titles on 25 pages), which is why i felt it important to emphasize.
that should never happen and would be an issue you should take to the support then. we're talking about the opposite here: the store pages for games you've bought in the bundle don't know you own them and ask you to buy the bundle (and/or individual game) again.
also, just for the record, yes, OneShot is supposed to be in the bundle, and shows up, on my account, and at the time of writing this, on page 21, ymmv.
yes exactly, that's the issue. unless you do that it tells you to buy games you already have.
since the store page already shows you the bundle (and asks you to also buy that again) they just need to add a "does the user have this bundle" check in addition to the failing "is it in their library" one.
