Rules:
I posted it as difficulty 4 and it's probably on the upper end of 4, this time. You have to find out some intrinsec, general pieces of logic to break cleanly. I will try to post a hidden comment with details on the intended break (shown after solving) if I can figure out how to do so.
Have fun solving it! :)
