Currently have two players on my server that have found a way to spam sell.  It appears they can introduce latency into the sell process thereby mass spamming during the window refresh.  I have the logs of them doing it and see them selling massive amounts of items in 1 sec intervals.  There really needs to be a cooldown in place or a way to prevent this.  If anyone knows how, I would appreciate it.  Hope the two doing it read this, then they will learn the fate that is about to hit them.  🤣
