First up, Neocash items have been moved out of a category dropdown selection into a toggle above it. To find NC items, you must have this toggle set to NC!
If you're having trouble finding your NC item, make sure NC is toggled!
In addition, some optimizations to load SDBs with very large numbers of items have seemingly been made. Previously, these would take almost a minute to load if they loaded at all, but now appear to load much faster.
Finally, perhaps to achieve this optimization, the "sort by" options sort only the items on the current page, instead of the entire SDB.
Unfortunately, the Safety Deposit Box is still built inconsistently with the Closet and Inventory, rendering our SDB Price Checker Tool unusable. If you'd like TNT to change this so you can easily check the value of your SDB contents, we've included instructions on the tool's page with how you can let TNT know:
The "sort by" was the only useful option of this conversion!!! 
Please TNT, I love Jellyneo but can't you give us a heads up when you are making changes so I don't freak out until JN calms me down?
Announce first. THEN update.
