1. Add three enemy units in a column spaced ~30m apart, like so:
<-A <-B <-C
Where the arrow <- represents the direction the unit is facing.
2. Move or teleport C next to A (or anywhere within max view distance).
3. Kill B with a silent/suppressed weapon.
Expected: Neither A nor C should detect that B has been killed as there is no line of sight and they are beyond audible range for a supressed weapon.
Observed: C immediately detects that B has been killed. A remains oblivious.
