Hi there! Sorry for the late reply, i just checked the page again, almost missed this. Luckily i managed to make it work! But kind of not the way it was intended, i had to start looting zombies like crazy and then the citizen card started dropping, the trader never gave me any, nor did i get any mission to receive it from the trader, in the end it still worked out.
Only issue i'm having at the moment is i cannot for the life of me get the special super charged engine for the Amelia Earhart mission, i also cannot find any info as to where i can get it, and i'm scared to think that i might have gotten one and i sold it by mistake, but i don't think so. My bf said he THINKS he got one by harvesting cars, so i've spent two days in game harvesting cars and i got nothing, i have salvage operations maxed out and on the second day i also ate a harvesting candy to see if i was just unlucky, but nope. Any tips?
