I've been storing my caravan cards in the doctor's house where you start and when I return to take them out, they disappear. Is this a bug or am I overlooking something?

bumpity bump.

When you buy caravan cards, they're supposed to "disappear" and end up in your deck. It turns out there's a bug in the script, so they don't get added to your deck when purchased (as opposed to being picked up). So if you pick them up out of a container, they will get added to your deck, but if you buy them they will just show up as individual items in your inventory.

So when you stashed them in the container, then removed them, they got added to your deck. To see all the cards you have, you need to challenge someone to a game of caravan, then go through the "deck selection" phase. You'll see the new cards in there - they have different backs and different face designs.

the container may be unsafe also, gotta be careful where you put your stuff

Thanks. Storing my stuff in Victor's hosue ATM.
