Per the Devs at https://forum-en.guildwars2.com/forum/wuv/wuv/WvW-Tournament-Rewards-Distribution-Delay/page/23#post4115826:
Tournament rewards for the World vs. World Spring 2014 Tournament will be available in the June 17th build. Once that build is live, you will be able to speak to the Battle Historian in any WvW map to get an updated tournament chest that has the correct rewards and number of tickets for your placement. Previously issued tickets will be voided with the build. Feel free to open any chests that you have already received now.
To thank you for your patience while we sorted out this bug, all players who completed the meta achievement will receive an additional 100 tickets.
Thank you once again for your understanding.
