Description of how the bug occurred:
1. Lock an item in your inventory.
2. Deposit the item into your bank.
3. Unlock the item whilst viewing it in your bank.
4. You'll then receive a UI Error that pops up on screen.
Effects of the UI Error:
1. You can no longer go back by pressing circle, resulting in the player having to press start to exit the bank.
2. The player can no longer "view more actions" (by pressing triangle) on gear, weapons in player inventory.
3. You can no longer send messages in chat, You receive another UI Error.
4. When viewing title in the character sheet you can no longer press circle to go back.
5. When viewing Mail the UI shows my character attributes overlapping the contents of my inbox, again unable to press circle.
As for all other UI sections including Collections, Skills, Champion, Campaigns, Journal, Social, Activity Finder, Help, Options and Log out, They all work as intended.
Hope this is helpful.
