Thanks for the report. We went through the history of your Parachute Agent Shoes: both Scrolls for Shoes for ATT passed (+2 each), and each Agent Equipment Scroll then re-rolled every stat the shoes had at that moment, anywhere from -5 to +5. The +2 attack was one of those stats, and both times the roll took it to 0 (the same rolls took STR, DEX and INT to 0 and raised LUK, Weapon Def., Magic Def. and Jump). That is how this scroll worked in Pre-BB MapleStory: it can enhance or worsen, and a stat that reaches 0 is gone and is not rolled again. Your shoes still have 1 upgrade left. Your idea of showing a rolled-off stat as 0, and your request for new shoes and scrolls, have been passed to Mark.
