So I am adding a small little keep in Westfall I am using same walls from Nethergrade Keep. I have no problem adding my map to my custom map patch, and my keep shows in the game. However, if I use blink spell I am able to go through the walls. If I test it on same walls of Nethergrade Keep the spell will not allow me through. So can someone help me with what I am missing here?

That's because your Vmaps are not updated to the custom map. Look up how to generate custom Vmaps
