ROLLBACK EXP and LOST SWORD

Here is what happen. We are party of 3 (RenzRampas, Toots and Me(badtripboy)). We are leveling in Mirage. I gained EXP of 86.00 there before i got killed by mobs because of disconnection. So my EXP became 84.46. I decided to go to FORTUNE to level alone. I gained 89.95% when RenzRampas was done leveling in Mirage. I sent a pm to him to borrow his sword for fast leveling. RenzRampas went to Fortune to lend me his 2 sword BOE +4 GOR +4 Lustrious. We exchange our sword and party for even faster leveling. He noticed something about my HP coz its blinking. He told me to restart my computer and log in again. So I logged out with his sword in me. I restart my computer and log again. When i got logged. I notice that we have the same sword. I expect that sword of RenzRampas will still be my sword when I log in. But in my suprise my old sword was with me and that sword of RenzRampas was gone and my EXP rollback to 84.46.

Hope you can help us retrieve the sword of RenzRampas (2 pcs BOE+4 GOR +4 Lustrious) and also my EXP.
