Issue running tests

I am getting this error when running tests: Your tests timed out. This might mean that there was an issue in our infrastructure, but more likely it suggests that your code is running slowly. Is there an infinite loop or something similar?
I even tried running tests on an empty file and it resulted the same error

This should be fixed now. Sorry for the inconvienience.

For Scala it is still happening, at least with the Prime Factors exercise.
