In Unity, this filtered out null and left it with a list of 2 elements. Any quick solutions?
Also, why does it need to be filtered in the first place?
Yeah, it has been that way for a couple of years. It basically comes from a limitation of the deserialization process.
Take a look at this thread for a workaround: https://support.gamesparks.net/support/discussions/topics/1000072083
I hope that helps.
