This is going to be a bit controversial, and I may not get support for this, but I will suggest this idea anyway.
As we know, making a headshot on most of the male animals in this game will result in not being able to taxidermy the trophy. This is slightly unrealistic as it is still possible to recover a trophy depending on the damage in real life. That is why I propose the idea of paying extra for a damaged trophy to be repaired. The price would vary from the level of damage and if the trophy is beyond repair the offer will be cancelled. This offer would apply to all male and (Horned/Antlered) female big game species, as females are exempted from the headshot rule that is already in the game.
I am open to hear your thoughts and criticisms.
