Occasionally when I take ore from the guild bank and log out, then remember I forgot to put back the remainder it is gone from my bags. Usually i can log out and back in and its there. Today i have logged out several times, and even closed out the game completely and it still is missing. this has been happening to me since DF launch. I can only recall this happening on my Blacksmith when I do my weekly crafting orders. Today I can’t seem to get it to show back up. this is becoming rather annoying because since i took out the entire stack, I either have to wait till it finally comes back, or buy some to complete my orders on my other toons.
Also, if I do get more from the guild bank then log out and back in, the missing ore is then in my reagent bag.
