An accident dupe.

i had some stuff in my inventory but didnt have space in vault so i decided to transfer it to my other account . we were both in nexus . i traded him transferred all the stuff i had (Ghostly , Astral ,Mana ) and then ran with the character to realm , by entering the realm i got into "account in use"
then i got disconnected after like 3 min of account in use .. and tried to connect again but i had to wait the whole account in use .. after it got over
i realized all the stuff i transferred still in my inventory !

Few details that might be the reasons:
1.after the second disconnect or the third i tried to press P which is reconnect key . and it has reconnected to Nexus once again ..(from nexus ,to nexus)

2.when i transferred the stuff and get to account in use , while i was in account in use i went to the other client to get in vault.

well this is how it happened .. still got no clue how it did work but i swear i have dupelicated !
