Is it safe?

Is it safe to add more then 1 million bp on your safe when the save game editor? or is that a risk?

There is risk of being safe.

Nothing is save when you hack, just do it @ your own risk. I set my bps to 99999999999999 in case the bloodpoint hacking is going to be impossible in the future.

Do what you want to do but don't cry if you get banned !
