Something that would be nice is to apply the current settings when bringing up the interface and to also bring up the same, what is the term...nomenclature?, terminology?, measurement ranges? (sorry having a brain kludge).
It is pretty difficult to translate the game's settings offerred on game creation compared to what is offerred on this interface's creation.
I just wanted to add a bit more salty rock and instead wound up with an entirely new landscape and wasn't aware until I lifted the fog-of-war.
Not the end of the world for me - I just filled my dance card with a bunch more landfill than I hoped for.

You can see from this image, https://ibb.co/XsmBnSw , that there is a clear delineation from the old to the new.

To the users, I suggest you generate, investigate and make the decision to continue instead of what I did, which is to blow it off for hours and regret your decision hours later. For me, it will indeed make the game more interesting and I look forward to that challenge, but it is not what I wished for.

** Sorry, I would have includedd pics of the interface for comparisons on the measurement/term differences, but I have already ditched the mod.

Changing biomes like this shouldn't happen unless you changed the seed. I can look at the save if you host a copy of it somewhere. There is probably a way to undo this.

A map preserves a copy of original settings, so it will be easy to see if the seed changed, or if some other change caused this. Mismatched chunks can be undone once the settings responsible for the mismatch are undone.

I totally realize this is a result of my own doing.

I think if I had dealt with it right away I probably would have been ok. Instead I didn't see any immediate difference because the changes happened in undiscovered chunks. Hours/days later, I realized that something was amiss.

The numbers, percentages, etc used for settings those values, are confusing from the original setup and what is offered in the mods options. In the initial setup, you are given percentages. https://ibb.co/GpQ2tZq https://ibb.co/TMrgnjw

In this mod, you are given the option of whole numbers. Is the user to assume that this is a percentage number, 1-100, or should be treated as 0-1? At any rate, it is not picking up all the settings/changes I used at generation. Note the ignored setting for enemies and note how 600% now equals 6. Perhaps there should be a note on the interface as to how the numbers work towards the originals value. Not hard to figure out, but I had to go back and reinstall the mod and create a new save to figure it out. https://ibb.co/s2sBxXp

I don't mean for my tone to come across as angry - just a suggestion to make your mod better :) A close button on the interface would also be an awesome addition!

These are very different things:

1. Finding 6 unaesthetic compared to 600%
2. Mismatched biomes
3. The UI possibly not initializing correctly with Pyanodon's ores

The UI is supposed to open with settings from the current map. It works in vanilla and Space Age. I will test Pyanodon's later. I would like to know if your mismatched biomes are a bug or a mistake, and either way you will be able to fix this if you want. But I no longer have time today.

I don't think 6 vs. 600% is important. I didn't create the mod. About 1,000 people wanted it updated, so I updated it. I will change the UI eventually and think about this then. But the other things are more important.
