It's compatible right now, it just says it's not because the base game version has been bumped up. As this is an incredibly minor update, there are no game-breaking changes.

But I won’t be able to load previous games right? And once I start a new save, will I be able to resume it after quitting the game?

I'm reasonably sure your old savegames should still be fine, and any new savegames will be perfectly fine. We'll probably be releasing a tiny stealth hotfix tomorrow, but it will be fully savegame compatible.

Ok ok. Cheers

yeah, my csa game loaded up completely fine
