Most likely.  This was a change to the GoWalla API... so it's going to break all the apps the same.  Seems the app is only able to retrieve the last page of your items.  I'll have to update the app to make this work now.  Thanks for your patience.
Believe this issue has been fixed. If you are still having issues, please reopen ticket with description, thank you!
Hi Stuart, Did you get the beta e-mail? I would appreciate it if you could check that my fix was successful.
Will be present in 2.71
That being the case then I think I have a good idea where the issue lies. Thanks again for your help, I'll try and put out a fix soon.
Thanks for all the hard work. I think what may be happening is that there is indeed the item you are looking for out there, however it is selecting the wrong location when it stops. While I work on this issue, you might try looking at locations near the selected location for the item.
I've upgraded my phone to 4.2 and I'm still unable to recreate this situation. Can you share your GoWalla user id? Also, if you are interested, I can put you on a beta testers list, and start sending you betas too. badpirate@logichigh.com
Okay, thank you Stuart. I'll get to working on this tomorrow.
Hi Stuart,

I updated to 4.2 and didn't have any problems. Perhaps your inventory cache is corrupted. Please try this:

1. Launch PirateWalla
2. Hit the back button to reenter your username
3. Enter your username again, but use a different capitalization (ex. "badPirate" instead of "BadPirate")

This will cause the inventory cache to be reloaded (caches are tied to usernames and are case sensitive). If this fixes your issue let me know, and I'll put in a proper reset button to the next version. Thanks!
