Hello everybody!
I am using the newest version of the Lotr-mod and also the new version of the Not-enough-items extension of Malvegil, which is really helpful in my eyes.
As I went through all the recipes, I noticed, that some of the recipes seemed to use a stack of four items instead of one, as they should.
Therefore, I suspected a bug in the NEI plugin and contacted the ranger, but he found out, that it is a bug in the lotr-mod code:
Strangely enough, the game doesn't care for that number. The recipe works like intended and takes only one brick as input. Even if you put in a full stack of bricks and a full stack of snowballs, it uses only up one brick per snowball, even when you right-click to craft.
It seems, that minecraft doesn't care for this number, and I woulnd't have noticed it, if not NEI would have displayed it.
Btw. it's not the only occurence in the mod, several brick recipes are displayed like that.
