I started the plot a few days ago and since Neopets left it open I thought I would be able to finish it in like a few hours or something. I got all the way up to the Dreamer constellation but when I tried to submit it, it didn't work. So I got annoyed and just decided to forget about it. Today I actually tried the plot again and I found I could submit the first constellation but when I found and tried to submit the second constellation it again wouldn't work. Is this how it works, that you can only do one part per day?
