Replay Tool: Characters Not Shooting When I Select Record/Replay and Other Problems

Hi, so the problem I've encountered recently has to do with the Replay Tool. I've tried to get a group of characters to shoot the automatic rifle all at once. However, after recording the first character's actions and I go to record the second and third characters, and so on, the rest of the characters do not shoot when I record/replay. They can still move around, but the rifles appear to not work and do not make any sound. If I replay the recording and I am currently selected on one of the characters, then, that character will begin to shoot and do everything I told it to as if nothing was wrong, while the rest of the characters remain as before. Sometimes when I have the character's spin around their body will turn while their rifles remain stationary.

Also, sometimes when I go to reload the world to continue recording or to replay the previous actions, my game session will crash and notify me that an error occurred when trying to load one or more objects, and send me back to the main menu.

I've included a compressed version of my log file (sorry, it was too big to attach as a regular file) and a link to a video that shows the issues I've encountered. The beginning of the video shows what I've tried to explain, and then towards the end of the video (5:15 minute mark) is where I get the error message to finally occur.

I hope that I've explained it well enough. Thanks!
