I have the same problem. I use YEP_CoreEngine with mgohunter menu plugin. and i have problem with Item upgrade. I cant use my item for uograde and when i put on rune item it put me this message "Cannot Read Property SetItem of Undefined"
Not about my game project but i feels like to talk about it a bit.
It's my コテキャ and maybe closest thing in english is a "avatar personality" i guess?
Her design also looks very similar to protagonist from my game because i'm so uninspiring
Oh and my hobby is sleeping and drawing.
