question about rollback

[rafael1234]

i have found out a way to get c/i will in trade and get realm down for 15 mins..im guessing it's a rollback..now how can i use it?

Does it give you your item back even though you sold the item? Just getting R/D doesn't mean its a roll back. Be more descriptive on how you did it also. If you actually did that, then abusing the glitch will come naturally.
