Guild Wars 2

Ok, I’m not sure, if this actually was a bug- or exploit, but this night I logged in and found around 44g in my trade post waiting for me. I was wondering where it came from. I usually do farming in my evenings and make about 30-45g from it, but I already had the money from the night before. I didn’t take it out, because I was afraid that it was some kind of exploit. My TP-history didn’t give me any clue. I relogged on a different character and a few minutes later back on my first character and when I checked the TP-window, it was empty (just a few gold from new sellings).
I’d like to repeat, I didn’t take the money, but I forgot to take a screen, because I wasn’t sure about it being a bug or maybe something I forgot in the TP.

This isn’t about getting the 44g, I just wanted to ask, if other ppl had the same “experience” and maybe tell some devs about it. Since I haven’t taken the gold, I can’t even say, if it will show in the inventory.
