"One of the routine maintenance tasks which run in the background has failed several times.."

I got this for these 2 system tasks: digest, profilesync
errors:

Error: Call to undefined method IPS\forums\Topic::averageRating() (0)
#0 /home/hwzone/public_html/community/system/Email/Email.php(1030): IPS\Theme\email_html_forums_digests__item(Object(IPS\forums\Topic), Object(IPS\Email\Outgoing\SendGrid))
 

TypeError: IPS\Http\Url::external(): Argument #1 ($url) must be of type string, null given, called in /home/hwzone/public_html/community/system/Login/Handler/OAuth2/Facebook.php on line 321 (0)
 

Are these two, yet again, related to some old files I should simply delete and get rid of?

Can you please post this in the bug tracker? Thanks.
