I kinda liked that they came back I did get all four jet packs in the beginning which took awhile, but I gave my colored ones away too people that were missing that one color I had I let them keep it more room in my inventory but all I wanted was the black one so it didnt matter

Then when i saw they came back I thought
" again...YES another black one for me"
When I saw that they lowered the kills I thought
"hm if I knew they would have done this I wouldn't have had to go crazy for a while"
Then when I got all the other three colored ones I decided to keep them to show I did it without the trading of others
