The game isn't line to line symmetry.
For example, you copy an odd move in xspar. You do it on another server and it may not work.
Some things are just random chance. Also, engage distance can play a role in this too.
If I go to a lobby where again, xspar is the mod; I do the move. It works out.
A couple days later I create the same move in the excact smae mod but with different eg. It may not work out this time.
Not all moves are like this. As for the most part, a well put together run can withstand these types of obstacles.
Sometimes Toribash is random, you gotta accept it x)
