I don't know, have you noticed, but Vircurex has been trading TRC since looong time ago and never done any upgrades so I am NOTsurprised over this:
2018-01-05: Hanging TRC withdrawals credited back NEW
An account audit of the TRC withdrawals of 2017 have identified various withdrawals that did not make it into the blockchain. We have cancelled those withdrawals and credited the funds back into your account.
2018-01-02: TRC wallet online again
Terracoin wallet is online again, we have received various inquiries about failed withdrawals in the past weeks. We are performing an audit on all wallet transactions and will credit back TRC funds into your account if the withdrawal did not make it into the blockchain.
Let's see what is their next move.
Vircurex decided to do us all a great gift for the New Year, when they updated the wallet and decided to return unsuccessful withdrawals. It is difficult to judge how global their goal, but about the seriousness of their intentions is the fact that in my case it was returned 10 000TRC unsuccessfully sent in September 2016 and at the current rate it's quite a decent amount!
