I figured it out, and this is what i had to do in case anybody does this. There is a custom struct set up called sQuat. When I moved stuff around the BPFL VR function library lost track of that struct and any inputs or outputs on functions that were looking for squat reverted to just regular structs, and any make or break squat nodes reverted to unkown struct. So I had to take all the inputs and outputs on these functions and set them back to sQuat, then rewire the broken make and break nodes to where they were before. I did that, and all the class blueprints that depended on those functions compiled correctly.
