Cryptopia has advised the following, not sure how to feel about it:
"We were notified of the UNB wallet update yesterday and have passed it onto our admins. The will update the wallet as soon as they can however we are unable to provide an ETA as to when this will be completed. This will also be dependent on the outcome of a wallet audit - wallet balance vs user balance. If there is a discrepancy we will have to talk to the dev about compensating our users for any lost coins."
