Thanks for the report, we are investigating the issue.@Kyronix -possible bug
I received the Tiger Cub statuette as a reward from the quest today.
Once the tiger cub was in my back pack, I could not take it out and add it to my bank box, it kept popping back into my pack.
I also tried transferring it via the trade window and it would go back into my pack and then I would crash.
I was able to drop it directly onto my guild mate and the transfer was successful this way but my guild mate also could not add tiger to his bank box either.
