(I’m literally here just to try to answer questions, so I’m obviously not bothered by questions 
)
Assuming (for now) that I didn’t mess up the second logic, did you set up the spline to go through the level (defining a path for the camera)? You should be able to just plug in the output white wire from “Set World Rotation” (first graph) to the “Set World Location” (second graph), which will perform both in sequence (causing the camera to both rotate and move towards the player). But if you just plugged in the second one, that should partly work too (you should get a camera moving as the player is moving, but not rotating).
Can I get some screenshots of your current setup and some more words on how the camera goes “flying until the map stops rendering”? Does it move without the player moving? etc.
