ArrayIndexOutOfBoundsException: 17

[jesus12345]

Well, I've noticed that when I open certain chests(ones that I believe contain a special type of wool, of which was spawned for me a while ago), MC crashes because of ArrayIndexOutOfBoundsException.
I'm presuming that this is because I placed these special types of wool inside these chests before the CraftLand mod came about, and these special types of blocks aren't included in the mod. Could I possibly get some help?

uhm... special type of wool...?
I have never known that there was special types of wool before.
What kind of wool was that?

Are there also other stuff in the chest, otherwise i could just remove it.

Will be fixed next update
