Copy / paste ?

[Pilou]

When I copy something, random result arrive when the animation start
Is that normal

[HFM]

Yes, it's 'normal'

since a hinge [or other connection] will get a name atached to it. Once you copy it it will try to react the same as the first one resulting in weird animations. Solution edit the connector's name and all should be fine.
