Major F**up in UPSC CMS

Hey guys, if anyone knows about this please let me know, during the filling of OMR sheet in paper 1 there was filling of paper code which was supposed to be 01 and instead of that I by mistake filled 26 that was my center code, rest everything else I assured was fine the roll number and everything, in the second paper I made sure everything is right though! what can be the chances of this paper to get rejected? 😭😭😭 I want to cry hard!!
