"500 error internal server error" after successfully completing a level.

Thanks for your help with the last issue!
I've run into another one. When I finished the last question on the last level of "neuter", I kept receiving a page saying "500 error, internal server error". I tried retaking the level on different devices and different networks with the same outcome, so I think it may be an issue with the site. I've attached a screenshot of the error and my level.

Hi again! Sorry you’ve been having these issues. I can’t immediately see what the problem might be, but I’ll look into it asap. I am a student, so providing rapid support can be a bit stretching, but I hope you’ll forgive me for the delay 🙂. I would suggest logging out and clearing your cookies, but that shouldn’t be a problem if you’ve tried it on multiple devices. What browser / OS are you using?

Oh, I'm in no rush at all, so take all the time you need! And I'll try logging out and clearing my cookies. I'm using Google Chrome and Windows 10 on both devices.
