im using ue4 4.12 and blueprints.
all trace results within my project is off to the lower right of the target.

the yellow squares are the targets i was looking at when calling the trace.
the green lines and particles are the traces results.
it appears as if the trace function is broken, the results are consistent across all trace modes and functions.
note: i am not skilled in programming, hence the use of blueprints.
