soul core of atmohua bug

1.I bought "Soul core of Atmohua" from currency exchange and could not take it out
as soon as i try to take it out game kick me out to login screen.

2.So i bought another 2 from trade site, then use them on "Chober Chaber Leaden Greathammer" and it seem like it doesnt work at all.
Not Convert 100int requirement to 40str(since i use 2 of them so it is 40% convert) more requirement on the weapon OR giving me 40 more str

.

this sh*t converts requirements to strength requirements. I ruined my gear cause of bad explanation of this garbage too, these soul cores need fix cause its unusable garbage with small benefits
