This is the proxied dll for the Mod-Manager.
Proxies all the exports of the stock amd_ags_x64.dll file, redirects to the original file. Searches for a list of mods, as would appear if installed with the mod manager, and calls loadlibrary on each.
Essentially its injecting a folder full of dll's automatically, as the game starts. Except its not injecting, since it's just calling loadlibrary natively from the game. You just point any dll that you'd normally inject, in the mod folder with its name in the file, and it'll get loaded right up.
