title: Laravel Chunk Upload skipping one chunk
body: <p>I am using <a href="https://github.com/pionl/laravel-chunk-upload" rel="nofollow noreferrer">laravel-chuck-upload</a> in combination with <a href="https://www.dropzonejs.com/" rel="nofollow noreferrer">dropzone.js</a>. Everything works fine, the chunks are uploading and when they are uploaded the final file will be saved in S3. The problem is that 1 chunk is always missing. Sometimes .8.part is missing, sometimes .7.part is missing (they remain in the chunks directory after uploading). When I upload a video that has a total size of 9.7MB the file in S3 is 8.7MB. That is 1mb missing, the same size as the missing part. All the chunks are 1MB in size.</p>
  
  <p>What could be the problem and how can I fix this?</p>
  
  <p>Edit: I think I have found the problem, but not the fix. When the last chunk (10th) is uploaded it thinks all the chunks are uploaded but the 8th chunk isn't finished uploading yet. </p>
