Error when trying to render latest message in LatestPosts widget from unknown author

[eLFuvo]

When author of latest post is removed I have this error:

Trying to get property of non-object
 in @vendor/bizley/podium/src/views/elements/forum/_forum.php

patch this please in src/views/elements/forum/_forum.php:24 as follow

if (!empty($model->latest) && !empty($model->latest->author) && !empty($model->latest->thread)):

and src/models/Post.php:338

$latest[] = [
                    'id' => $post->id,
                    'title' => $post->thread->name,
                    'created' => $post->created_at,
                    'author' => $post->author ? $post->author->podiumTag : null,
                ];

or fix those methods by adding relation check

public static function getLatestPostsForMembers($limit = 5)
    {
        return static::find()
            ->joinWith('author', false, 'INNER JOIN')
            ->orderBy(['created_at' => SORT_DESC])->limit($limit)->all();
    }

...

public static function getLatestPostsForGuests($limit = 5)
    {
        return static::find()
            ->joinWith('author', false, 'INNER JOIN')
            ->joinWith(['forum' => function ($query) {
            $query->andWhere([Forum::tableName() . '.visible' => 1])->joinWith(['category' => function ($query) {
                $query->andWhere([Category::tableName() . '.visible' => 1]);
            }]);
        }])->orderBy(['created_at' => SORT_DESC])->limit($limit)->all();
    }
