• Opted into Steam client beta?: No
• Have you checked for system updates?: Yes

Please describe your issue in as much detail as possible:

When running SteamCMD to download and install updates for the ARK: Survival Evolved dedicated server (app ID 376030), I get spammed with the following error message for every workshop Mod I download. This message appears 8 times in rapid succession for every workshop item downloaded. This becan with the most recent update to SteamCMD and effects all SteamCMD isntallations on the system. I have attempted re-installation of SteamCMD but it did not correct the issue.

I have been informed by others that this is not limited to workshop content from a single game (ARK: Survival Evolved) but have not personally confirmed this is the case.

It does not appear to interfere with the download process itself, but it makes my logs VERY chatty and causes difficulty locating specific items within it.

Error Message:

contentmanifest.cpp (650) : Assertion Failed: !m_bIsFinalized

Steps for reproducing this issue:

1. Run SteamCMD and download a workshop item (Workshop items for the ARK: Survival Evolved server are still referenced using the PREVIOUS app ID of 346110 instead of the current app ID of 376030).

./steamcmd.sh
@ShutdownOnFailedCommand 1
@NoPromptForPassword 1
@sSteamCmdForcePlatformType linux
login anonymous
force_install_dir "/home/steam/ark"
app_update 376030 validate
workshop_download_item 346110 899987403

1. View output and see assertion message spam:
