it doesnt have to be cracked for it to be a problem.
it could be hazy, or still, it could just be pushing the eyes out of alignment. see if you can push the eyes back a little with your fingers, then put the eyepipe in.
OR, put a new eyepipe in, and see if that fixes the problem. if the eyes still go to default, you know its not the eyepipe but an alignment issue.
