Re: xml edit interface [bug]
The Bug that your character will not update cannot be fixed if using 2k8 files, the only way to properly fix this is to create a new Character Viewer just meant for lobby so that the shop/ equip versions are unused.
tl;dr: This cannot be fixed without editing the source code.
Re: xml edit interface [bug]
It's best to just leave everything as it is if you don't have the source.
Off-Topic: Those are some big buttons!
Re: xml edit interface [bug]
You better make those buttons a little smaller, but thanks for using them anyway. and for you problem, just leave the interface as it is.
