materialItem[1002]...

Anyone know what it is?
Been trying to get a few Centipede's Poison for the +200 ATK Maga, but I only keep getting those materialItem[1002] drops. :/

They don't replace rare drops, they seem to drop from all enemies alongside their other items. They're probably related to the baskets released with this patch somehow.
