Lag? that's a pretty poor excuse especially when a mob is standing still on a slight hill and i get the "too far away" message and i'm standing next to it but a mob that gets itself stuck in a tree sure doesn't have a problem hitting me
and that PS2 ram thing is a horrible excuse to apply to everything. sure adding new content will take up space but changing a variable (like changing an item to stack 12 or 99) should be nothing but a variable.
