Was doing 3v3 and 4v4 ffg games on some custom maps that i'd made. They were mostly just modified official game maps with extra oil derricks , more ore, or air units disabled. I never added any trainers or anything crazy to these maps.
In a 3v3 sedona with crates disabled I noticed that one of my allies who was America made a Boris from an allied barracks. Even crazier was that he was targeting not just enemy structures but enemy tank units using migs with a distance way across from his own spawn. I then questioned him about it and he just blamed the map that I made and that he was only using the mods built into the map. This was a lie. He was going by the name Johnson. I said I was gonna report him. He said it didn't matter since he could just use a different ip and a different nickname.
We continued to try to play on various other custom maps that I made, but he continued rejoining on other nicknames. Almost every match he would freeze my miners to where I couldn't get them to mine or deposit ore. My units would also lose the ability to auto attack enemy units. There was also a ton of reconnection errors. Sometimes within the first 5 seconds of the game start. I imagine something to do with whatever mods the guy was using.
Finally I gave up playing for the day when he started freezing me and other players miners, disabled auto attack, but then also began selling other players structures for them. All day I had other players in my gameroom complaining about this guy hacking our games. I even had some people accusing me of being the cheater. I know very well that I never added the ability to do these kind of cheats on any of my custom maps. Unfortunately I wasn't able to test if this guy could also use his cheats on an official game map, but lets sure as hell hope not.
