Add unique to vector array crashes editor

Hey all. I’ve searched and haven’t found anything like this so I’m hoping someone can help. I’m working on a dynamic subdivision blueprint that makes a base hexagon mesh and is able subdivides the triangles of that hex to n degrees of subdivision. In my build hex section, I’m using sin() and cos() to build the hex dynamically inside a for loop, and it all works as expected. However, I initially built the blueprint using Add to add a vertex vector to my vector arrays. This of course leads to having multiple instances of the same vertex vector value being stored in the array. So, I decided to try to use AddUnique to maximize efficiency. I started with one node and everything behaved as expected. However, as soon as I added a second AddUnique node and tried to compile, the editor crashed. I’ve repeated this several times, so it’s reliable. Any ideas what would cause this?

And secondly, since I’ve gotten into the habit of saving before compiling, now my project crashes on startup. Can I just edit the AddUnique nodes out of the bluescript uasset file? Or am I SoL and have to recover from backup?

Any advice would be greatly appreciated.

Cheers,
