Commented Unassigned: Unterminated String Error Downloading Tweets [2299]

Hi!

Trying to download a bunch of tweets, I usually receive this error:
```
[Newtonsoft.Json.JsonReaderException] = {"Unterminated string. Expected delimiter: \". Path '[41].user.listed_count', line 1, position 245530."}
```
This always happens to me after a while downloading tweets, but if I restart the program, It will happen again (for example, I download a list of tweets, and after I receive the error, I delete the downloaded file, play again the program, and the error will popup again, but not at the same moment as before)

This is the part of the code that makes the download:
```
IEnumerable<ITweet> tweets;
List<ITweet> historicalTweet = new List<ITweet>();
long maxID = 0;
try
{
do
{

var request = Timeline.CreateUserTimelineRequestParameter(ticker);
request.MaximumNumberOfTweetsToRetrieve = 32000;
request.MaxId = maxID - 1;
tweets = Timeline.GetUserTimeline(request);

if (tweets.Count() > 0)
{
maxID = (from tweet in tweets
select tweet.Id).Min();
historicalTweet.AddRange(tweets);
}
}
while (tweets.Count() > 0);
}
catch(Exception Error)
{
var exceptionStatusCode = ExceptionHandler.GetLastException().StatusCode;
var exceptionDescription = ExceptionHandler.GetLastException().TwitterDescription;
var exceptionDetails = ExceptionHandler.GetLastException().TwitterExceptionInfos.First().Message;
Console.WriteLine(exceptionDetails);
Console.WriteLine("Error downloading tweets: " + exceptionStatusCode + ", Details: " + exceptionDetails);
}
return historicalTweet;
```


And this is the StackTrace:

Thank you!

Hi!

This happened for different users in different moments. I noticed that if I repeated the request, starting from the ID of the tweet that failed, it worked.

Therefore, I just made a condition that if the download failed, make a new request starting from that last tweet.

Thanks!
