Not the neopets ad blocker, but maybe the ads from HotSpotSheild etc.
Many people (including me) use proxies, and some of them have HotSpotSheild, which always has an ad on the top, which causing ABrosia to not work (?)
2. Shop Changer
Not sure if we have this, but it changes shops every refresh.
/Refreshes Magic Once/
/Refreshes Coin Once/
/Refreshes Magic Once/
And so forth.
This could be randomized, so it could be 2 @ magic, 6 @ coin, 4 @ magic, and so forth
Lots of people dont just restock in one shop :\
