Holy Smite error in Boomsday Project

I was playing The Boomsday Project Lab 2 (Cloning), adventure mode, just for fun and nostalgia. But in the first challenge of the episode 8/8 you have to clone the border using the Holy Smite Spell which at the time of the Boomsday project caused 2 damage but nowadays it causes 3 damage. So it makes impossible to complete the challenge. I hope you guys fix this simple error.
