Invisible Red (x)

Estaba en el desierto Almuj, me encontre con un esqueleto con cabeza de wither que al matarlo me dropeo una X roja, al cojerla el juego se crashea y ya no puedo entrar. Algun consejo? Apenas pongo el raton sobre ese item que esta "invisible", no lo puedo ver, se crashea.

I was in desert Almuj, i found a skeleton with a wither head, after i killed him he dropped me like a red (X), when i tried to pick it up the game crashed and now i cant even join. The item is in my hotbar and is invisible, every time i try to drop it or just click on it the game crashes. anyone can help me? Ty

This bug also appeared in the Beta, although I had heard it was fixed. You should submit a Bug Report.

 

I found the bug. The invisible X was a totem from 1.12, if you update the game 1.9 to 1.12 you can see it. Ty
