TL;DR: Eloquent models are updating, if I dump the object the attributes show correctly, but when I query the DB it is not correct. Code:

public function store(Requests\CreateDIDRequest $request)
{
    Log::info("Starting DID creation");
    $DIDs = [];
    switch($request->input('did_quantifier'))
    {
        case 'list':
            Log::info("List of DIDs given");
            $raw = preg_split ("/\\r\\n|\\r|\\n/", $request->input('did_list'));
            foreach($raw as $did)
            {
                preg_match('/\d{10}/',$did,$match);
                $DIDs[] = $match[0];
            }
            break;
        case 'range':
            Log::info("Range of DIDs given");
            for($i=$request->input('did_range_start'); $i<=$request->input('did_range_end'); $i++)
            {
                $DIDs[] = $i;
            }
            break;
    }
    Log::info("Iterating through DIDs");
    foreach($DIDs as $tmpDID)
    {
        Log::info("Building {$tmpDID}");
        $newDID = DID::firstOrCreate(['did' => $tmpDID]);

        if($request->input('customer_id') != '0')
        {
            Log::info("{$tmpDID}: Assigning DID");
            $data = [
                'customer_id' => $request->input('customer_id'),
                'service_location_id' => $request->input('service_location_id'),
                'name' => $request->input('name'),
                'address' => $request->input('address'),
                'address2' => $request->input('address2'),
                'city' => $request->input('city'),
                'state' => $request->input('state'),
                'zip' => $request->input('zip'),
                'inuse' => '1',
                'flhsi_tn' => '1',
                'did_network_id' => $request->input('did_network_id')
            ];                
        }else
        {
            Log::info("{$tmpDID}: Not assigning DID");
            $data = [
                'inuse' => '0',
                'flhsi_tn' => '1',
                'did_network_id' => $request->input('did_network_id')
            ];
        }
        Log::info("{$tmpDID}: Data:");
        Log::info($data);
        $newDID->update($data);
        if(!$newDID->ratecenter)
        {
            $newDID->updateRateCenter();
        }

        $IncomingExtension = CVRExtension::firstOrCreate([
            'context' => 'incoming-direct',
            'exten' => $tmpDID,
            'priority' => '1'
        ]);
        $OutgoingExtension = CVRExtension::firstOrCreate([
            'context' => 'outbound',
            'exten' => $tmpDID,
            'priority' => '1'
        ]);
        $IncomingExtension->update(['app' => 'Goto','appdata' => 'incoming-unused,s,1']);
        $OutgoingExtension->update(['app' => 'Goto','appdata' => 'incoming,${EXTEN},1']);
    }

    //return redirect("/did");
}

As far as the DB goes, it looks like no query happens after the initial firstOrCreate, data is not updated at all on the DID model, but the CVRExtensions are created and updated correctly. Trying to find out why it isn't persisting the data to the DB.
