Uso o manual em inglês versão 2016 para tirar minhas dúvidas.

Minha opinião:
1 - pode reconstruir sim, mas lembre-se que, quando você perdeu o item, perdeu também a comida não perecível concedida pela barragem (salvo se já havia sido consumida).
2 - itens de cenário não sofrem esse efeito, então não há como os reconstruir.
During the game, an effect may force players to flip Items back to their Invention side. From the start of the following round, such an Item ceases to be available
(it is still available for the current round). It must be built again before it can be used. If a personal Invention is flipped back to its Invention side, it is returned to the side of the appropriate Character sheet. It can also be built again, but only by the owning character, who gains another 2 Determination tokens when doing so. Items on Scenario sheets are never affected by such an effect.
If a flipped Item is required for any Actions in the same round, they can still be resolved. Since the Item was available during planning (and while assigning Action pawns), the Action remains valid and is resolved as if the Item were still present. Built Items that had the flipped Item as a requirement are not affected.
Effects of Items that apply in the current Action Phase (e.g. neutral Action pawns or the effects of Basket, Sack, or Bed) also remain available throughout the
Phase, as they were available during planning. Actions using these effects remain valid and continue to use the cards’ effects.
If an Item flipped to the Invention side had an additional positive effect, it must be reverted if possible. If the effect is only partially reversible (e.g. not enough food or Weapon level to discard), revert as much as possible. Being unable to (fully) revert a positive effect has no negative impact on the players.
Examples:
• If you lose the Dam, you must discard 2 nonperishable food. If you don’t have any, nothing happens.
