Try this:
Make a big circle object the size of the prox you want, not solid, circle shape, layer 3, have collisions. Alpha it barely visible, ~20 should be fine. Attach it to the player. Use collision with circle for the enemies, so they activate when you touch them with the circle. If it works, Alpha 0 the circle and you have a workaround. If other enemies trigger and you didn’t touch them, clones are super broken.
