[spoiler]
which gong piece did you drop? are you sure you lost it and it isn't in the research hut? (if you don't do the brambles to uncover the gong assembly site, the pieces get stored in the research hut.)
i know if you drop the one from the crate, it will reappear if you leave VV2 and come back. i suspect the same is true of the others.
it took my villager several tries to get the crate gong piece to the gong assembly site. he kept getting "caught" on the edge of the hut nearest the crate area because there were other villagers in his way i guess. once he didnt make it because a celebration was called. i did not see him drop the gong piece but i noticed him partying and there was no gong piece at the crate or at the gong assembly site.
i don't think villagers should drop gong pieces to celebrate!
