Decided to go along with DP's advice of injecting files via the updated patcher, rather than wholesale .mod replacements. Making the .utc list in changes.ini alone will take me five thousand years, but I feel it'll be worth it. This will also allow the installation to be simplified considerably, as the main bulk will only require one run for all the changes to be applied, with two optional patches that can be run after. One for M4-78, other for Extended Enclave.
