I am currently trying to update a mod for Arma 3 but every time I try to push the update I get the error on the attached file. It only happens with this and I have tried the following things.
Re-opened both the publisher and Arma 3 Tools
Restarted my computer
Moved the folder to a different drive
Removed Special characters from the Changelog and Description
Deleted all text from the Changelog and Description
Uploaded it as a separate workshop item (upload succeeded)
I've not been able to find any helpful information on why this is happening
Cleared my steam Caches and reinstalled steam
