We have been looking into reports of higher than expected numbers of Shared Bank Storage slots since the release of Update 43, and have identified the cause. The issue is that the new 10th Anniversary Free to Play Launch Bundle is erroneously granting its 10 Shared Bank slots to VIP players whether the item was purchased or not.
However, we are happy to report that we intend for players to retain these additional slots in the next game update. VIP players, along with Premium Players who have purchased the Shared Bank, will see an additional 10 slots, because moving forward the base number of Shared Bank Storage slots will be 30, up from the usual 20.
Those who purchased the 10th anniversary Free 2 Play Launch Bundle will see an extra 10 slots granted to them on the next Game update.
