clarkwinkelmann Here you go:
production.ERROR: TypeError: Argument 1 passed to AntoineFr\Money\Listeners\GiveMoney::giveMoney() must be an instance of Flarum\User\User, null given, called in /vendor/antoinefr/flarum-ext-money/src/Listeners/GiveMoney.php on line 80 and defined in /vendor/antoinefr/flarum-ext-money/src/Listeners/GiveMoney.php:35
It turns out this only happens when you delete a user and then try to delete their post. Which makes sense since the error is pointing to user\user being null.
So this extension is compatible, but not when it comes to removing deleted users posts.
