My whole Springfield town has gone nuts they walk through walls and walk on water it is so annoying they can even walk through buildings I presume it is a bug.
No bug. Thats how the game works. Quit whining.
i have played the game for months and it has only just started particularly the walking backwards I get the walking over water and through walls if objects are in the way but not walking backwards.
I noticed Marge walking backwards today. It made me laugh!
