Description

Line trace component appears to return a hit result even when the trace should not have had anything to hit. Attached project shows line trace start & end points. Even when the trace doesn't overlap the other character it will still print the "hit character" message on occasion (about 1 in 15 traces).

Steps to Reproduce
  1. Download attached project
  2. Double click .uproject to rebuild dlls and open project
  3. PIE
  4. Position controlled character next to stationary character facing the same direction
  5. Press LMB repeatedly to trigger line trace

Result:
The line trace will occasionally indicate that the stationary character was hit by the trace even though the trace is not passing through the character/capsule

Expected:
Line trace is consistent when trace distance & target are both stationary
