I removed the img tags in your post as they forced every visitor to this page to download huge image files.
For some reason your attachment has disappeared in the process, which I did not intend. Maybe a forum bug?
Anyway, obviously we provide patches and updates with working shaders. If you use modified shaders maybe you should keep the originals backed up so if there is a change you can install a working set until your custom shader developer updates his or her shaders.
We are going to update the shaders sometimes, it's part of the development process.
