Yes I will give details. I bought about 600-700mill worth of average hp citrine shards, I kept combining the shards until I had about 700 flawless hp shards. I then went afk for 2 minutes while they were crafting into level 8 gems. When I came back I went to craft the level 9 gems but It said I didn't have the correct materials. So when I looked into my bag I still seen the 700 flawless shards in a stack so I thought that maybe I didn't press start or it canceled for some reason. When I went to make the level 8 gems again it said I didn't have the correct materials. So I thought my inventory was just glitching and I was talking to my guilds at the time so I know I wasn't force logged. I relogged which took about 3 seconds. When I got back on all of my flawless shards were gone and I didn't have any level 8 gems.
This is the entire story/Process as it happened.
