»My items in /pv 1 disappeared

After the maintenance, when i had logged in to get some stuff from /pv 1, it was literally empty, I thought it was a normal glitch which gets fixed after 5-10 seconds but nothing happened, I tried like 10 times doing /pv 1 again and again to see if the items come back but nothing happened. Later on, i put 1 item in the vault and it fitted so technically, my items were gone and there were like 300k+ items, I hope I can get my stuff back later on...
