Line Trace won't hit certain actors, regardless of channels/objects?

Okay I solved my problem with Event Tick. It has a tendency to skip certain objects when I only execute the line trace once. I also found out I can’t disable or enable the Event Tick node or it will cause the same problem. The line trace literally HAS to continually run in the background, forever. Or it wont work. I’m very confused, this cannot be good for performance.

This is still not 100% miss-proof, as it seems.
