I'm not sure if this is a new bug or user error, but Skritter won't let me add new words from one of my lists at the time being. I stopped adding words a few days ago to prepare for my test that I had yesterday, and then I changed the settings on my textbook's list to skip some sections because we're skipping those chapters in class, then I restarted adding from that list. However, no new words are being added at all. Whenever I restart adding from the list, it spontaneously returns to "stopped adding" as soon as I start to study without adding any new words. It's not as if I don't have any new words to add - there are about 100 on the list in unskipped sections that I don't know.
I hope that was a clear explanation of what's going on. This is kinda bugging me, no pun intended.
