Nah It was my own fault. I misread the instructions, specifically the part about trying to avoid getting the "???" gold figure, I believe it was. I revertered to an old save and stopped increasing my dps before it became "infinite" thus (I presume) causing certain integers stored in memory to overflow and causing my gold to break the game. After doing that everything works as planned.
I'm not sure about getting flagged as a cheater, though. Is that stored in a .plist file somewhere that can be altered? One would assume they store that info sever side but hey ya never know. Either way, though, if I'm flagged as a cheater it doesn't seem to have made much of a difference for me. I still get grouped with people who clearly are not cheating for tournaments.
