Thank you.
The reason I didn't test it with Zombie is simply because I've never used that command before and reliable UI display is fundamental to game development.
The layers were so deep that only a very observant person would notice, so I'm including a link, but there's a video saved that actually shows all skills increasing the damage of all weapons.
If this is a "local environment bug," then nothing would make me happier, but my friend has also...
It's obviously different from the xml and skill description, but isn't this a bug?
I have heard that it actually exists based on the results of at least one person's testing.
"Increasing any weapon level increases damage for all weapons."
