NBTEditor v3 compiled as of commit c3a72b1

/nbti var Name &btest

Doesn't change the name of the item to a blue "test".

Thanks for reporting, should be fixed now.

@goncalomb I'm getting reports that this still isn't working. Not able to use a color code in the name to colorize items. Such as with /nbti var name &bhello. I'm guessing using color codes in the lore would also be broken if it doesn't interpret &<code>.

Edit: Testing myself to confirm, it seems to work fine. So I'm not sure why he wasn't able to use color codes. However I did notice there is a bit of delay before the item updates with the specified name / color code. Maybe because of the delay, if you open your inventory after typing the command, it doesn't refresh the item?

I'm not sure how the delay affects the update of the NBT tags. It may be caused by the server not sending the updated NBT tags to the client right away (I don't know how the internals work). As far as the NBTEditor is concerned, all the NBT changes happen on the same tick (there is no added delay).
If it becomes a problem in the future, I'll investigate it.
