This has now happened to me on two different characters, the first happened after a bg ended while I was dead, I left the bg and and was still dead. I used a soul gem and noticed my appearance was not the outfit I had applied. I /reloadui and nothing changed. I went to an outfit station and the slots appeared to have the specific styles for each armor/weapon slot I had saved for my outfit. I /reloadui again and still nothing. I use the outfit station again and everything was no longer applied.
The second time this occurred I accepted a bg queue and ended up stuck in the loading screen. It eventually timed out and I was logged out with the error along the lines of "lost connection to lobby". I log back in, and in the character select it looks like my outfit is applied like normal. Once loaded, my character was dead and styles no longer applied. I did not go to an outfit station this time but tried logging out. I log out and in the character selection screen my character no longer has the applied styles from my outfit.
I'm out over 16k gold now, and when I submitted a ticket I was told to submit a bug ticket which was immediately closed so I opened another which was flagged as duplicate. I have lost currency in the past due to bugs and was told to kick rocks, seems like a counter intuitive customer service policy but ok. If this is standard that's outlined somewhere in writing I would appreciate a link so I can lower my expectations.
