Larger character count for generation settings

We can have up to 4000 characters for instruction blocks even at a free level, and those run every single turn. Generation settings only ever need to be considered when, you know, generating something; yet they are 500 characters each. That’s super limited. How the game generates is a super important part of any world that you would want to be able to control with detail. It makes sense that their limits should be increases, especially considering how they are only ever used in specific situations as opposed to every turn.

Also, when clicking edit on any of the generation setting texts, it deletes the entire text and makes you start over instead of letting you edit the already existing text.
