@Gummibeer Nothing to pressure but I am not sure if you were notified about this so just pinging.

Have you run Larastan test on this and it fixes @Gummibeer issue?

It seems that this issue introduced these errors on larastan:

Call to method where() on an unknown class Spatie\Activitylog\Models\Illuminate\Database\Eloquent\Builder

anyone experienced something similar?

I think that's because of a missing \

@method static Illuminate\Database\Eloquent\Builder|Spatie\Activitylog\Models\Activity query()

shouldn't it be this?

@method static \Illuminate\Database\Eloquent\Builder|\Spatie\Activitylog\Models\Activity query()
