This is pretty typical of PhD students that make others work for them (that's not what is expected of you, you are not a professor, you are their assistant) and don't have good professors to help them learn good leadership practices. They take too big of a task and aren't good managers yet and have to deal with a crowd of unreliable workers. Undergrads are notoriously unreliable due to a lack of experience, high confidence and low time flexibility. They often have high course load and finals, must find their next lab and so on. Also as an undergrad when you see your project leader beeing lost, you look for an escape and put your effort in things that will matter more (you very well know that paper will not be written in time) because you know that nothing will get out of this project in a reasonable time frame. My 2 cents if you are stuck in a situation like that, put in a single document everything you have. All the methods you have used, the results. These are easy to put and do not require any creativity. Then you start explaining context, concepts and what you planned and where it could lead. No need to make pages. Make lists. After that everything is about fluffying those lists at your own pace. Writing is almost never a linear endeavor, even more the first time you do it. Whatever happens being you finishing that into your article(s) and dissertation or quitting will at least make sure that nobody worked for nothing.
