I have modded 3 account so far. Two has more than 1Bil each and the third is my alt I use for money drops.
Leveled each from 1 to 100 and unlocked all.
No issue so far, 4 days later.
Stealth cheat works, for the most part. But I don't recommend going over 1Bil. I really didn't need it like I thought I would.
