Rockfall damage in the field of vision

Something I didn’t worry about so far has arrived. A stone flew against my disc. Hinterliess a “jump” in the size of a 20Cent piece. Of course, exactly in the middle of the field of view. I have so far got everything almost smoothly for my vehicle, with a disc probably stops. The Lord of Carglass just said that they can’t repair this because it is in the field of view. He wants to try to get a disc, but I’m not so optimistis h. Someone a tip for me? What options do I have? Can one have something like this also “unofficially” repaired to gain time first? Thank you
