Mod not updating correctly

After changing computers my Mod now uploads as a new Mod instead of updating my old one. Is there a way to match up the Mod IDs again so that the new comp pushes to the old mod?

yes, there is. There is a config file that holds your settings for upload.
It is located here:
yourArkDevKitDirectory\projects\shooterGame\Saved\Mods.db
Important Note- I do not know if these settings need to be changed prior to cooking the map (resetting the GUID does.)
So you may need to cook after making a change first.

Open that .db file with a text editor (I prefer notepad ++)
In that you will find a section with your mod
replace the number following “ItemSeamId” with the workshop ID for your original work or your workshop submission you want to replace (this should be the number listed at the end of your workshop item link.)
For example “http://steamcommunity.com/sharedfiles/filedetails/?id=547828060” is the link to my Roraima workshop item. 547828060 is the “itemSeamID.”

You can also change the title to whatever you want with no effect other then what will show as the name on the workshop page. It’s still technically the same workshop submission.

First, sorry for the double post, these posts would not show up for me at all until two days later so i thought they were failing.

The only approach that has worked for me is incredibly convoluted.

  1. Upload from Dev Kit. (will always make a new mod now even if i change the mod.db file.)
  2. Delete that new mod through the website
  3. Now my .vfd is valid and I can alter the PublishedID in it to the old mod’s ID
  4. Now I can run SteamCMD and upload it that way.

Absolutley nothing i do can upload the mod from the dev kit anymore. If i try to just edit the .vfd ahead of time it will not work unless i have previously uploaded from the dev kit to an incorrect mod. I have no clue why, a dif of the files returns that they are identical.
