Q:
Gold Disappeared from TP
Gold is treated the same as items in the pick up window, if you have a lot of items in the pick up tab, gold will not show up until some of those items are removed.
If you got gold for something else that was posted after you removed your buy order make sure that you didn’t get the item you were buying, or if you picked up items with a different character your gold might be on that character since the trading post is shared by all characters on the account.

I lost some money too some time ago, ordering 3 globs of ectoplasm I think, the money just never came back.
I did not bother to report it, because of the small sum, but it is definitely possible that the TP bugged for you aswell.
