Sudden Rating drop during contest

In today’s contest - starter130, i submit 2 questions within 10-15 minutes but still my rating dropped from around 1550 to around 250… Then after solving 3rd it came up again to the 1550 approx. I wanna know why was that the case ?

I think that was an issue that happened with all users, I got my rating dropped to 240 as well and then it went back up.

Same here. It probably bugged, but fixed after the next refreshing

So the current rating fixed right? Will it get changed again?

Yeah It happened with me too.
I had the same question yesterday that will it affect the actual rating change if it didn’t have a drop.
So is the rating change according to original rating?
