When I used Studio today and tried to rescale this mesh part, this happened:
Some part with size 0.05< may also have issues with scaling of 0 studs (they start to move to other direction slightly when you try to scale and this is still occurring since a week before)
Haven’t found any posts about these bugs
Its pivot issue go models tab and reset pivot
Its just a glitch that happens you scale down your part past 0,01. To avoid that simply don’t scale past that amount, and use custom set increments as a safety that won’t allow to reach that size.
refering to first video, this happens because the mesh only has 1 face, extrude it in blender and it should be fixed
