Sorry if this isn't the right place to ask for this but it says "compatibility" in the description and seem to be about enabling/disabling modules as standalone. I have read the descriptions of the mods "planet Balack" and "planet Wit", and it doesn't explicitly says if it's possible to add to an existing game or if it's not recommended. It says "post Aquilo" for the planet Balack for example so i'm tempted to add it to my pre-Aquilo save game and ideally i would also add the modules that works without starting over.

I would also understand if a new game is required, it's fine, i'm just a bit lost about wether or not it make sense to try and add the planets to an existing save. I would follow a "recommended full experience modpack" for my next game if it's not recommended to add to a new game.

Cool, I tried to make it add-able to existing saves in the sense that it wont crash. BM: Hunger will cause you to starve so I would make sure you are near bioflux or fish to eat if you add it. BM: Industry will change a lot of the basic recipes so you would need to redo elements of your existing factories. BM: Wit change recipes for space science and lasers so you would need to redo those on wit. BM: Radioactive tissue makes biolabs consume u-235 instead of energy. BM: Balack and BM: Homeworld should be add-able without any problems.

If you install BM: Modpack all standalone modules in BM: Core are activated by mods it contains. The standalone settings are for partial modpack downloads (including just BM: Core) to activate the modules to your preference. All the main BM mods (hunger, wit, etc.) download the standalone modules that I felt were useful.

Thanks for pointing my vagueness out, I will update the descriptions later.

Descriptions are updated

Nice to get an answer, and also this answer is nice to hear , makes it easy to test a planet quick before the full modpack
thanks for the updatated description

Great, let me know if you run into any issues in your test
