Version 1.4.0.29

I have been unable to add a contributor to my unlisted mod 'Frontline Core', GUID 654285B306EEFC33.

Previously if the user's email was not found I would be prompted with User not found, and I know the user I'm trying to add as a contributor is being found. Publishing works fine without them being listed in contributors, and I even tried adding myself to see if it would work and it published fine.

I tried changing visibility, had the user create a new account, link their steam account, etc. Nothing seems to be working.

Log of when attempting to publish can be found below.

BACKEND (E): [RestApi] ID:[110] TYPE:[EBREQ_WORKSHOP_CreateAssetUpload] Error Code:404 - Not Found, apiCode="remoteRequestFailed", uid="1748440795177-64005", message="Remote request failed"
DEFAULT (E): Uploading failed! Reason: "Remote request failed"

I tried this with 2 different mods and they both gave me the same results.
