Here are few more examples of the issues:
New Thai Favourites – May 6th had 12 spots open
Jasmeen Bains buys 2
there are now 4 sold and 8 spots open (instead of 10)
And just now, “Weeknight Healthy” sold 4 tickets, which should have sold it out, but instead the stock jumped up to 24
There doesn’t seem to be any rhyme or reason to the random stock changes!
