Quake remastered models mod Ironwail crash – From /r/Quake

Does anyone know how to get the Quake remastered models expanded mod to work with Ironwail? The mod works fine with the official remaster, but trying to use the mod in Ironwail crashes the game, whether I choose “Remaster” or “Original” when I first start up Ironwail and have the remastered models selected in the options.
