A thread on forum.dominionstrategy.com (Inheritance and Nomad Camp
) revealed an (esoteric) bug when inheriting Nomad Camp (or generally an Action card with a non-default gain location, but I think Nomad Camp is the only one at the moment).
When buying Estates in that case, they become 'yours' (and hence have all abilities of Nomad Camp) before they are gained, so they are gained to your deck.
When gaining them in another way (say Workshop), they are just Estates before the gain, so are gained to your discard pile (where they have the Nomad Camp ability, but which is now "to late" to apply).
Dominion Online gains the card to the discard pile in both cases (incorrect for buy, correct for other 'gain').
