Odd behavior at the Ticker market stalls this past reset

[Craaazy Teds Discount Car]

Someone else reported that the two stalls next to each other seemed to share the same items  in their books regardless of the contents of the boxes.  I did not see that, but someone told me that happened to them.

What I can say is that the sign seemed to be resetting very rapidly this past reset and not always at the same time interval either.  I can't speculate as to why.
