If MrPlow is looping endlessly over a few items follow the instructions below:

1. Take note of which items are being swapped. Be aware, that it will almost always involve at least 3 items at most times.
2. use  /mp add [Blocky Item of Block][Womble cabbage of Frog][Fried Green Tomatoes] (use shift-click on the items)
3. run /mp sort and copy/paste the resultant output to the ticket (after hitting /mp stop after it loops)
4. note /mp watching and /mp clear will show what's being monitored and clear the list respectively.
