Vertex Map Crash

[Martange]

Hi,

I have a vertex map in C4D that drives the mix between two textures... Fairly standard. But everytime I open a node editor with a vertex map as the amount of a "mix material" it crashes C4D.

I can erase my vertex map node beforehand (without opening the node editor), replace it afterwards and begin to work with it again without any problem. Then, if I quit and reload the project, same crash happens as before when opening the node editor.

Attached is the bug report zip folder.
