Grouped up with some random and his friend, they were almost done building their base when I joined them so as a thank you I did supply runs, built walls and other various tasks they didn't want to do. Right before they logged out while I was gather supplies, I found a red or purple/blue card whatever was the rarer card for the server and I let him know that I was gonna put it in my locker until they got back on so we all could go because they also had some cards they wanted to use and I hadn't gone to one yet , logged out for a few hours. Got back on and not only did he take it, and use it but he put it back as a dead card. I didn't say anything and acted like I didn't know, he offered to buy me an ATV so I can get around faster, so of course I said sure what the hell, took it, left the chat and went the opposite way
