Hi MuhRoads,
I’m actually not sure on this one. I don’t have any of the plugin’s installed on my UE4 installation. I’m also not a programmer so when it comes to modifying code and such as you’ve done and some of the things it affects I’m unfortunately at a loss.
To better serve your question I’m going to retitle this post and move it to the “Engine Source & GitHub” section to see if someone there can assist you as this seems more likely related to Rama’s vertex snapping plugin. He may be able to help you look at the issue as well.
Thank you!
Tim
