Where can I go to sell stools?

At random times throughout the day The NPC's get stuck at spots near my tables. and just walk in place until restart. and or without a thief around to take/steal your items at random times while I'm watching the NPC's eat the chairs or tables just randomly get deleted for no reason. so I have to buy new ones........ anyone else having this problem?...

I got this bug like three times today, some stuff dissapeared after some customer got stucked, especially chairs. There is no thiefs so I got confused..

The store's not opened. its gate open only half and i cannot get in there to buy bomb and Mirasgg. How can I do? I already reinstalled the game but not solved

I am curious to see if it is possible to edit save files. The game is built in unity, so i am not sure if this is possible...
