I think you have a distortion that is not quite right because maybe at that time was the hard fork for BCHN (Bitcoin Cash Node).
If I'm not mistaken BCHN (Bitcoin Cash Node) has just been done, because maybe you also wrote in this thread it's November 16th and now it's November 19th.
The possibility of this happening is when Bitfinex is recording Hardfork, a suspend deposit occurs and you deposit so that your BitcoinCash is stuck in the middle of the transaction.
Indeed , I started the transaction 3 hour prior to that time and 5 hour before hard fork time.
The transaction had 18 confirmations , but hasn't been credited to my account. Even when the deposits\withdrawals were opened.
I contacted to support and wrote several emails and
After 3 weeks , today the coins were credited.
Telling the truth, I already accepted I had lost them forever .
Of course , I realize it was completely my fault.
Thank you for comment. And my regards to bitfinex team, they could easily keep the coins because It was my fault
