I was just making a model of a rocket. It involved a lot of making groups and cloning lot's of stuff, and at a certain point, I realized the brick count was a lot higher than it should have been. Indeed, in some places there were almost 8 identical pieces inside of each other, and I had no idea how they got there. IDK if it was me and there's something I don't know, but that caused me not to be able to make a render... 😦 PLEASE HELP

BTW, the link for the model is here: https://www.mecabricks.com/en/models/r0DvYBl8a9e
