I was sorting it fine earlier today but now I can not get anything to drag at all. Does this just sometimes happen? I started having the issue a few hours ago and decided to leave it alone and try later but it is still not working for me.

It's working for me, but it does seem to be a lot slower than usual.

Odd, it still does not work for me. I will leave it and try again tomorrow. It is not a huge deal. I just don't want to get too many collected and have to sort them all at once. Thank you for commenting though.
