Broken: version: 2.92.0, branch: master, commit date: 2021-02-24 16:25, hash: `rB02948a2cab44`
Worked: (newest version of Blender that worked as expected)
**Short description of error**
When instancing objects with particles on vertices and then when you manually scale the object that the particles are on, the particle scale does not change, only the location, but when the object (the distribute object not the object that is instanced) scale is driven by a driver then the particle scale also changes for some reason.
**Exact steps for others to reproduce the error**
When scaling the object that the particles are on, everything works correctly, the particles stay at the same size they are supposed to.
But when driving the exact same scale variable with a driver, for some reason the particles get scaled
The property has to be on another object than the particle system, when it's on the object with particle system, then everything works as expected.
Pressing "Update Dependencies" fixes the scale, but in my real project that is unfeasible thing to do, I have many parameters that are driven that need to be animated and clicking them all through each time I make a tiny change is not possible. Also, rendering does not always fix the scales either.
