I noticed something peculiar. I bought a list from our SERLIST heroes, and threw that into my projects.
At some point I checked how many remaning urls I have. I had something like 180k at that point.
I then stopped SER, and restarted it. Now when I looked at the remaining urls, it was over 300k at that point.
Is this a feature of some sort?
I will say that I got curious about this after I noticed SER slowing down (almost stopping altogether) after running it for like an hours or so.
