Newly added mod will not be loaded

[jordanzhu]

I searched through the web and couldn't find an answer to this. 

I had successfully set up the server on a linux machine some days before, and I have 14 mods enabled, which all worked fine. Today I tried to add two more mods to the existing world, but they don't load. I do so by modifying the dedicated_server_mods_setup.lua, appending the two ServerModSetup("...") to it. Then I modified both modoverrides.lua files in Caves and Master folder, with new mods enabled properly like following: 

["workshop-466732225"]={ configuration_options={  }, enabled=true },
  ["workshop-666155465"]={
    configuration_options={
      chestB=-1,
      chestG=-1,
      chestR=-1,
      display_hp=-1,
      food_estimation=-1,
      food_order=0,
      food_style=0,
      lang="auto",
      show_food_units=-1,
      show_uses=-1
    },
    enabled=true
  }
However, after I done these steps, when opening the server again, these two mods won't load. I tried updating the game through steamcmd and that doesn't work as well. I looked through the log:

The bolded part doesn't include the mods I added. It seems to me, that the dedicated_server_mod_setup.lua is not loading this time and "modindex" loads the previous mods but not the new ones. I am not an expert at lua so I might be wrong, but is there any ways to force the mods to be downloaded and loaded without starting a new world?
