I'm using latikai - so could be that

I too get this error, occasionally. Upon reboot my item is in the stall.

My item also makes it into the stall during the crash.

Hmm I remember this error from Plymouth times

I never had it on Jamestown - owned two stalls there.

Well, it isn't caused by the custom clients as that ShopBox class is loaded from res files.

I do notice that the line numbers don't match up against anything sensible on the default client, at least. Please reproduce on default and post a proper backtrace.

Does it happen on some specific kinds of items, or just about any?
