Chipped Crankcase help!

Hello fellow KDXers!
I put a small chip in the right crankshaft seal "seat" when trying to remove it, see pics.

On a scale of 1 to 10 with 10 being very serious and 1 being barely serious...How serious is this damage?

Is it fixable? How?
If not say why.
Other concerns?

Thank you all!

Bike is 2004 KDX200

No I do not, this actually happened last year.

IMO, that is rated a 0 = non-issue. It is only the depth stop for the seal and doesn't carry any load. The only thing I would do to it is file/grind/sand it smooth and forget about it. I would only do that as to relieve any possible stress risers.
