First is the bug. My Sim is no longer able to Invite Over to Current Lot because I chose the Master of Grudges Aspiration once. The only choice I have available is to Trick to Come Over. It does not matter that I am not pursuing the Master of Grudges Aspiration, once it is selected as an Aspiration, the Invite Over to Current Lot is no longer an option and Trick to Come Over is the only option to get another Sim to come to current lot.
Second is the possible interaction behavior. When a Sim has a negative Friendship relationship with another Sim, Invite Over to Current Lot results in the other Sim refusing to come over. This would be overcome if any Sim could Trick to Come Over any Sim with a negative Friendship relationship. My preference is to see Invite Over to Current Lot for any Sim with a positive Friendship relationship and Trick to Come Over as an option for any Sim with a negative Friendship relationship.
