Combining the two ultra-rare add-ons from Amanda Young cancels one of the drawbacks.

Spyd

Amanda Young's add-on "Amanda's Letter" allows the killer to see the auras of survivors 16 meters from the killer when crouched. As this is an extremely overpowered add-on, apart from being ultra-rare, it has the drawback of reducing the number of reverse bear traps by 2.

But if you combine "Amanda's Letter" with "Videotape", all 4 survivors start with a bear trap, cancelling the drawback of "Amanda's Letter".

I know this is not technically a bug, as "Amanda's Letter" description says that you start the game with 2 less carried bear traps, and 0 - 2 is still none; but the problem I find here is that this add-on is overpowered by itself, but if you also add another very potent perk that also negates the drawback from the first one, that borders on cheating.

Maybe if combined, two random survivors would start with a bear trap, and two without. It makes sense, if the killer only start with two traps because of "Amanda's Letter", only two survivors should start with the bear traps installed when combined with "Videotape".
