***Needs to be recreated for compatibility with July 2023 version of Halo MCC.***
I added the step-by-step instructions in a Change Log file in Miscellaneous Files for how to recreate the mod using Assembly (available at https://ci.appveyor.com/project/ThunderWaffle/assembly/build/artifacts).  Due to other commitments, I will no longer be taking the time to recreate it.  However, if anyone will to put in the time (about 16 hours) to do it, as I have many, many times, I'd be happy to reupload it here and give credit to whomever does it.  Thanks!

Instructions:
Download and manage with Vortex.
