Timescale Issues(Making a replay function for game )

I am trying to create a replay function that involves using timescale for slowing down the players of my games . The issue that is coming up is that am able to slow down the scene using timescale and a new event but another event which is in the animation queue gets executed in the background and is skipped . I have tried reversing the time corresponding to that event using a reverse factor of timescale I used but it does not seem to work.(If i used Time.timescale = .1f i am reversing by multiplying the player time by 10).Has anyone ever faced the same issue please make me aware regarding the same .
