Hi folks, I’m barely scratching the surface of Unity and PB, however, I already hit a very annoying wall. Whenever I create a prefab (say, a wall piece), put down some instances, then want to change the original, therefore change all instances, it works in a weird way. So when I add 3 instances in this example, then modify the original prefab, it applies the shape changes. But when I go back to edit the prefab again, it will not apply the latest changes… what could be a problem? I looked over Google ofc, but I found no solution yet. If anyone can help me, my gratitude would be eternal 
You should file a bug report about that.I f modifying a prefab works once it should work again.
In the meantime, modifying the instances in bulk and overriding the prefab seems to be the way.
I should’ve been more precise, sorry for that. So, the material changes do carry over to the instances. However, I managed to take a screen now which shows that the changes in terms of object boundaries do apply to the instances - it just doesn’t “fill up” so to speak. Here’s what I’m talking about, see attached. I modified the original prefab, pulled a top face upwards. The instance shows the modified shape, but that’s about it…
