Hello there,
Thank you for reaching out to us.
We understand that you're experiencing an issue with the Portal's submenus. Having reviewed the provided video, this does seem strange to us. We've taken note of your experiences with the Currant error code. If this is occurring on Steam and you haven't already done so, you may wish to [url=https://help.steampowered.com/en/faqs/view/6AD7-820D-8BE5-E51F]Clear the Download Cache[/url], to see if that addresses this issue.
If that troubleshooting does not address this issue, then please let us know if it seemed anything in particular, apart from the Currant error code, seemed to precipitate this issue. We'll then review.
