Re: Core Modifications + BP Upgrades…
Well, it really depends on *what* core mods you’ve made, exactly. Without knowing what you might have done it is impossible to comment on.
As a rule of thumb, though, you can make a lot of changes without needing to modify the core files. If you’ve made a “few” already, maybe you could revisit them and see if there is a better way of reimplementing those changes.
