Answers marked right no matter what they are

In some of my lessons (mostly Swedish, I think), I'll run into a problem where it marks my answers as correct even if it's very obviously not. I don't mean simple typos, but things like misspelling the word beyond recognition, entering an entirely wrong word, or even accidentally hitting enter after only one letter. It doesn't always do that, but it happens maybe once every few days. Any idea what causes this?

You are probably disconnecting from wi-fi in the middle of a lesson. It's a reported bug. You can learn how to do it on purpose from a future hacker by clicking here.

That is to hacking what opening a packet of crisps is to cooking.
