maybe its ghosts? there is a glitch called ghosts items that happens when too many items on the ground and they get automatically deleted but still there in your view but not on others.. just reset the room i think or re-make the game.
its fine... i mean for the other slots atleast consider those two so you wont spend those pd's on buying materials... plus its easy to get materials when rare mobs is on... red is a good id too so you'll be fine it drops needle's as well on bringers i think.
on a level 1 you can go on episode 1 for levels 1 - 100(towards the future maybe) up to ultimate difficulty setting, then episode 2 for 100 - 200 (respective tomorrow) unless you are planning to hunt things along they way while leveling. if you plan on using rangers... i would recommend the following items a spread needle, cannon rouge and frozen shooter for your starting weapons... there are also thing you may want to consider like make an oran for obtaining hp materials and greenil for power materials and luck materials... if you make a room for ttf maybe someone will join... well eventually someone will help you out...
happy gaming i hope you enjoy your stay...
