Warning: Even though they thought this was fixed, it just happened to me again!
Per Myles! - They are 99.99999% sure this has now been fixed.
I don't know if many people are aware of an ongoing problem with the SDBs, but since I imagine a lot of people will be using them - and likely trying to add large quantities at once - I wanted to bring this to everyone's attention:
There is a known bug that causes items you are depositing to vanish. For me, it happens when I try to add all of an item in my inventory EXCEPT for one. (I like to keep things in the same place in my bags.) You get the message that all of the item could not be deposited and find that it is all gone from your inventory AND it is not added to the SDB. It doesn't happen every single time, but often enough. I've lost a crapload of resources to this insidious little pest because the staff keeps thinking it's been resolved. The only relatively easy and consistently safe way I've found to add a large number of items to my SDBs is to select to add half at a time. And then do it again. Rinse and repeat.
Please do not jump on me for "attacking" TS. I'm not. I know they are working on fixing this while also working on the other changes and fixes. It has been a royal pain for me, but I'm taking it all in stride. I only bring it up here, now, because I assume people will be trying to refill their previously stuffed SDBs with their mega-stashes of resources. I don't want people to lose a bunch of stuff because I didn't say anything.
