Interaction bug and corrupted objects making the game unplayable

Hi everyone, I encountered a bug today in the sims 2 legacy that makes me unable to have any interactions with other sims or even objects. 

After an interaction with a sim outside of my family, all the interactions that came after were immediately canceled and my sim got reset. For example, the options to talk to other sims were gone except for special greetings and even then, those options when chosen were immediately canceled and the sims reset. I noticed then that my sim was unable to interact with anything except themselves and all actions were also canceled when selected. Now, objects are getting corrupted (its losing their texture and colors) and any interactions is impossible.

I tried playing after the new patch was released but it did not correct this bug.  Also I don't use any cc. Does anyone had this problem ? For now, the game is unplayable for me so I hope to find solutions...
