I think what he is saying is that when he renames a weapon and saves the kernel that it resets to its original name when he exits WM. My item and weapon changes always take effect but I recentely encounted this same problem when trying to edit the name of a summon under the "attack" column. ( Im trying to have summon attacks be limit breaks, the character will learn the limit properly, it shows the name of the summon under the limit break menu, but in battle it doesnt appear)
