Items disapearing from AH

Sometimes when u add a new item to sell on AH, u get fee charged but items vanishes, item is not on sale list and u wont get back item by mail neither the paladium for sale.

I had the feeling , but i wasnt sure till 30 mins ago that i added some legendary mods very fast all of them for same cost on sale and when i have looked if they were on sale 2 of them had disapeared.

i think the problem happens when u add items fast on sale , but its a big bug cuz u get the fee charged, and u dont get the item, neither paladium neither salvaged mats.

known bug, listed among others in a document linked over here: Known issues list and bug report form
