As for phials; Please submit a bug report for that as you're the only one encountering that error.
As for the oak larders: please make sure to start the script exactly as the thread states. The script is not as fast as you could manually do it, I am aware of this. This is due to many factors, one being that you'll get banned too fast if the script is faster then it currently is.
