Yeah I tried all this before I asked and nothing helped. This particular BP is tied to the entire game so at some point I will clean it up with your method but this isn’t a solution also who knows if I grab all the nodes I will end up getting this invisible corrupted node and add it to the “new” BP.
This particular BP is so core to the project that I might end up just converting it to C++ which is the only I know I will get it clean.
It would be cool if someone created a converter so I could open the file in a text editor and then convert it back to BP. I wonder if I used the C++ header converter and ran that on a copy of the project I could see the corrupted node?
