When my max was 2400 I tried to edit the value to 1900 and it still caused it to get stuck on 1900 and snots stopped working. The research windows recognizes the edited value and let's me buy stuff, but snots won't build anything thst costs gold, they will idle and mine gold, but the value won't raise in game. Not sure how I could show you if it's not very clear :S
I appreciate the effort and the gold cheat works perfectly fine now. But this time the Evilness has issues. After a while, it's value freezes and won't change anymore. But that's not game changing at least.
