I had an exotic cipher from xur a week or so ago, but then it disappeared from my inventory. It is not in the vault. I got another exotic cipher from triumphs. However, as I just checked, that is also now gone. This is unacceptable. Exotic ciphers are important components of the game. Very important. It seems like this will keep happening unless it is addressed. I would like an exotic cipher back, and for it to not disappear like the last two. I was looking forward to obtaining an exotic of my choice this weekend.
