Just took a look at files concerning Guns in Game.
I found the same Gun in 3 different files and all have the same ID's!
My work list keeps getting longer.
Now here's my thoughts on this.
Given that there's probably a bunch of Guns with the same name and ID's?
There's probably not an ID conflict.
Which version of the gun is loaded is any bodies guess though.
The SH4 version or one of the SH3 versions.
NOW! Rename just one of those Guns and keep the same ID?
You'll have a conflict and probably a CTD.
The other problem is wasted space on the HD, a larger then needed download package, (Which leads to eating more bandwidth to Download it all), and a possible unstable situation.
