Trapper CANNOT pick a trap after setting it
The Trapper cannot pick up a trap after setting but can pick it up IF it's a re-setted trap.
Only way to to so is to walk away from the trap until its white aura is visible and pick it up.
This bug was introduced 2 patches ago and it's still here.
EDIT: This was tested on the PTB today (15th) and it's still here.
Thank you for your time.
