I have a large complex model I am working on. When I hit ctrl+d to update the model I get the error:
However whe I select the bus everything shows up correctly:
The bus is created using the bus creator block. I thought it might be related if/else blocks and merge blocks, but I created a simple model using these blocks and had no issues with the bus. Any ideas?

Thanks for the quick response Ravi. I had tried saving, rebooting etc but with no success. See my answer where I found the problem.

That’s a strange way to comment a block in which a signal propagates through it. Anyway I wouldn’t recommend doing it. Even if it doesn’t directly affect the functionality of what you want to do. Good that you found out the reason.

Ok, I guess I should have done a little more debugging before posting, but maybe this will be helpful to others. It turns out Simulink doesn't like you to comment through a block and then put that signal in a bus. I had several signal like below populating the bus. For some reason the bus creator and selector blocks have no issue with it, but when I do ctrl+d there is a problem but simulink debugging doesn't point me to the problem. When I removed all these commented blocks the issue went away.
