Yes! This will solve so much confusion!

 

Fiiiiiiiiiiiiiiiiiiiiiiiiiine, I'll go yell at Necro.

 

I definatly agree to this. It would make trading a whole lot less confusing, and also safer.

 

"Iron Bars" is the official name for iron fencing, this is not a convention, or mistake, it is the actual vanilla name.

Removing ironbars from the official file is a bad idea and breaks support for some client mods.
ECC could run it's own file, though.

Necro just added some extra names to the item list, including:
ironfence
jailfence
ibars
ifence
jfence

 

The main problem with removing things from items.csv is that signs that used names that got removed will become useless, the sign will be unbreakable and your items are lost forever.
