There are...a number of things that can go wrong with the A321, if you don't fly her properly...
The rudder does not activate until several dozen feet AGL.
Come in too slow (like I usually do because I fly it from short [grass] fields, not proper airports) and the throttles will lock in TOGA mode, forcing you to do a go around. AFAIK, there is no override for TOGA mode, apart from turning off the flight computers, which is dangerous. You can also do the same to regain control of the rudder.
However, it does not look like you experienced any of the above...was autopilot on at the time you were descending?
