Unable to unlock Relic Hunter achievement. Could only unlock 2 out of 3 relics. Which ones are considered relics?

German translation sounds kinda unfunny and has some spelling mistakes in it :/

Just started the game after the update to v1.2.1 and my savegame has disappeared, the only option I have is "New Game"

I wanted to pick up the rope. He climbes up but took the anvil? It looked like it. But then the game got stuck.

I built the Phallerhorn before using it to find the hamster (according to the guide I looked up when I got stuck I need it for this) and it won't let me feed the flies to get the hamster. Is there an alternative or am I stuck?
