The thing is, though, I've never seen it do this before until a few days ago.
And this isn't the only problem I've had with TBT. Sometimes when I send TBT to someone, I do it so I have exactly the amount I need to send. For example, if I needed to send 250 for a collectible, then I would make sure I had 250 TBT in my 'wallet'. It would clearly say I have 250 TBT, but when I try sending it, it says that I 'don't have 250 TBT to send'? This has never happened to me before until recently.
