Yes, this was done in Cloud Edit. it randomly happend before my friend even joined.
EDIT: This also happens in Edit mode! Meaning it doesnt have anything to do with it being in Cloud.
Happen to have a repro file of it?
Happen to have a repro file before unioning? All I am getting is corrupted child data.
EDIT:
I tried reverting the version of the place. But all i could get is the base part which is in version 8,
and then the completed version which is 9.
I think that’s all about what I can do.
To start off, I used 4 cylinders for making this union. The first cylinder I just pressed union on selection and scaled it to a greater size. I then copied it and put it on the other side of the part that’s supposed to be unioned.
I then selected both cylinders, copied them and rotated them so they would appear on the other sides as well.
I selected everything at once and pressed Union.
I didn’t touch it at all after that.
