My rating has been in a free fall due to Scala solutions not running in Codeforces for the last couple of contests. Please see:
They work fine locally and they randomly fail with this error:

Can CodeForces please rerun my submissions and update the ratings?
Auto comment: topic has been updated by wrick (previous revision, new revision, compare).
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.
