So, do you think that by some stroke of genius they could be using this as a way to catch cheaters?
If it loads every time it is available but is not required to spin before refreshing/going to another page, it could stay up for a little while while Abrosia is running. I have no idea the difficulty it would be to change Abrosia, but if possible perhaps a check at the start to see if Trudy's Surprise Slot Machine is available? If it is spin, and if not continue restocking.
