Short description of error

Material suddenly became emissive, but not for all objects using it

Exact steps for others to reproduce the error

I think i just applyed it to the object and it became emissive. But there are other objects using this material, and they are not behaving like that.

In addition, 10 minutes eatlier a friend of mine sent me a msg saying that this happened to him. Not it happened to me. Not sure of the build he is using, but probally not the same i am.

Now everything else became dark

It´s weird because the upper part of the wall seems to be working :

Cycles works fine.

After rebooting the computer, the material which was black now is normalized.
But the other one is still emissive.

The textures are missing in the file. Could you pack them into the file and reupload it?

Can you figure out exact steps to reproduce the bug using this file? Everything looks normal to me.

was that to me or Clement?

Because i have no idea on that case.

But it just happened to me again, and it happened when i changed from cycles to eevee (i am now using build 1fc75dbbce).
The materials came back to normal when i added a new blank material slot on the object that had the problem.

Also it just happened to some of the faces when applying the bevel modifier
