My user profile simply says "Stats are being refreshed, page will reload when done", and has done for hours now. New Katas I have completed in this time do not seem to have affected my rank or honour.

Is this usually a long process, or has something broken?

Aha! I found where I was going wrong. I was not removing comments correctly, so I was getting erroneous characters in my inputs.

Thanks anyway!

I have a problem with this test case:
sststsstssstsntnssnnn

My interpreter is doing this:

ss : Stack manipulation - Push

t stsstsssts n : -290

tn : I/O commands

ss : Output character`

This fails because -290 is not a valid character

Can you advise where I might be going wrong please?
