There is a problem with Vaultex.io exchange.
I bought nearly 1500 FAIR yesterday and made a withdrawal.
My FAIRs just lost. TXid bbf5b4207d941299697aeeba2c59d9ac3699d455a3d0aa21803f54afd791a48f - not found on the blockchain.

Seems that we have to exclude this exchange from the list of working exchanges.
