The bouquet throw at wedding events results in the sim walking around aimlessly with a bouquet and occasionally waiting for wedding guests to gather behind them. After guests gather the sim walks to another spot to repeat the process. I looked to see if others had this problem and saw on other sites where people said to select a sim to specifically throw it to but those option weren't available to any sims that gathered behind me.
