Titan chest asking me to contact support to open!!! Really?
It happen sometimes normally if you open multiple at once I’ve found, just wait a while for the servers to catch up and will prob be ok without needing to send a ticket.
i also had this once. i sent a ticket, got compensation. just do it.
You can try to log out and log in again. 1 minute fix. Happened to me 3 times so far.
Its associated with the bug of opening too fast chests, and item count gets cluttered. I have reported it.
Despite that, make your screenshots and be sure to know date/time in case its not fixed the way I said.
