@BenVenNL I’m just guessing but there might be something that doesn’t get reset when you work with an object. There was that kind of issues (still is?) with center off mass for example. You had to use code to reset / reposition it. This was one thread about it (just in case you are interested.):
Nowadays I try to print out everything I can if I even half-suspect there might be something weird happening, even if it’s most likely my own mistake.
