Just because you didn't have any problems doesn't mean that others didn't.

As far as I am aware, it could be used to duplicate items, the display could get very buggy and in some instances it could corrupt worlds (i.e you lose your world forever).

All-in-all it was the most unstable mod in Tekkit Classic and removing it was a very wise move.
