I flew to the Cayman Islands and tried to buy 20 banana orchids and the site timed out when it was processing the purchase ( I assume that's what the small dots are xD ), when i refreshed the page I had been charged $80,000 and it said I had bought 20/20 items so I flew back to torn thinking there was no problem but when I landed back in torn I checked my items and it seems I was charged for 20 but only received 1.
I have no screenshots as I didn't think there was a problem.
I assume there are logs that can show this, I'm sorry I can't give more information or screenshots or anything.
Oh yeah it happened around 30-35 minutes before I made this post i would estimate but it may be slightly longer ( just incase this helps for checking the logs ).
