PP bolt broke off into flywheel

Ok so i'm getting my trans rebuilt to z spec and putting my KC clutch in finally.

While tightening the pressure plate bolts, one broke off into the flywheel :nonono: . I've ran cars before that were missing one bolt and i never had any problems. I even did a clutch for a friend and his was missing one bolt and he hasn't had any problems, albeit he drives like a grandma.

So should i worry about it or not?
