Offshore oil is not being added to
surface.map_gen_settings.autoplace_controls & surface.map_gen_settings.autoplace_settings.entity.settings
after adding the mod to existing world

Thanks for identifying this as a migration issue. Will try adding it to the existing surface parameters in the next update.

still not working...dont have offshore oil in existing world :(

Hi, sorry we forgot to address this. Would you be able to share your save file to make it go faster? If you have a copy from before you migrated to 2.0 that would be helpful too.

dw I've got a save that reproduces the problem - it doesn't need to be from 1.1 to see the bug, I just made a 2.0 non-cargo-ships save. I've fixed it so that when you add cargo ships to a save, it will now automatically enable offshore oil in that save. But if I make it so that when you update to the next version it also adds offshore oil then that will enable it for people who deliberately left it disabled. So instead I'll add a command to allow you to opt-in if you want.
