SEGFAULT when quadtree updates

[Patchnote-v2]

Happens on checking if any items have moved. For some reason it happens on a range-based for loop to check if items have moved.

for (auto item : this->items)
{
    if (item->hasMoved())
    {
        // ...
    }
}

When examining the memory it has a valid item in this->items yet somehow item is null and produces the SEGFAULT.

I need to figure out how the loop is setting item as a null object in the first place, as it should only loop through any items in this->items, which upon inspection were all valid.

This is no longer a problem as the old quadtree implementation has been scrapped for something simpler.
