I just lost an artifact mythril greatsword due to putting it on the market too high. Values over 1 trillion(to my knowledge) are listed as 1 gold. Please fix this, or put an error message when you attempt to put up an item at such high of a cost.
This will be "fixed" in the very near future. An error message will be returned to the screen in an invalid price is used, rather than defaulting to 1 gold. This was originally intentional well over a year ago, but the game has evolved past needing this crude corrective measure and proper error handling will be put in place.
