I'd like to know if there is a best practice when updating an installed mod? If I have mod v1 installed and mod v2 comes out, I normally let the new version overwrite the old and leave both installed. I'm wondering though if I should a) uninstall the original mod and then install the updated version b) install the updated version and then delete the old version c) continue as I have been, overwrite the old and leave it alone. Thanks for your input.
