Clockwork knight statue reset?

I was beginning to gather the suspicious marbles around the map to prepare for the shadow pieces. After I put the clockwork knight statue head on the statue when I next came back the clockwork knight head was no longer there and the statue is reset to how it was before ever mining it to reveal it was a clockwork knights body. Am I now no longer able to get all three of the chess sculptures now aka never being able to fight the shadow pieces? I’d like to also add I had to rollback a few times in the days after placing the statue but I never rolled back to before I finished the clockwork knight statue so it’s no longer on the map where I got it from it’s just completely missing.
