I've noticed that the gold option does work, you turn it on, wait a min and then turn it back off before you spend it. If you try to spend it when its on then its going to get all wonky and put you in a massive negative balance for most of the match, however if you activate it, let it generate gold and then turn it off, before you use it, works just fine.
I see. That's a really impractical change since in the game you always have familiars set up that level characters for you. But maybe an update in the game code forced this / made it necessary to remove the editor? At least the speedup works but onehitkills would be really useful to have to work again for when you reach your wall.
