Players are reporting they cannot access the small stash on the minis after the latest update. 

I have the same issue. Small stash is shown, but not able to open it.

Correction: Can open it, but must point to the bottom of the stash, or just below it. Only then will the "Open" option be shown.

I am unable to open the small stash at all no matter where I point. Moving the pointer around on the small stash either oppens the large box or else puts me in the pilot seat.
