Scala solutions failing — bug in runner
By wrick, history, 7 years ago, In English

My rating has been in a free fall due to Scala solutions not running in Codeforces for the last couple of contests. Please see:

29977952

29890121

29874042

29999130

Can CodeForces please rerun my submissions and update the ratings?

Ouch, that must hurt...

I believe asking to rejudge rating from several rounds back is a bit too much, but at the very least your results should be revoked.

And I hope the runtime issue can be fixed before the next rounds. We should be able to use the language that is officially supported on CF.
