I'm getting an error message when I edit a method

Hello all,
I keep getting this message when I try to edit a certain method

Error editing object:
edu.cmu.cs.stage3.alice.core.response.UserDefinedR esponse[world.Yellow cube in front of red cube]

This happens with all back-ups of the file not just the final one but the strange thing is that the method still works because when it is called it does what its suppose to do but when I try to edit it it shows the error and opens the method which it blank but it still does what it suppose to do

So anyone who knows what going on here please help me
Thanks.

I do not exactly know what is going on, but I experience bugs like that all the time.. (really annoying and time-wasting)

If the method isn't too complex, try deleting it and making a new one just like it. It will most likely be faster than trying to solve the bug somehow.
