U5 L10 - is there a bug that is not allowing completion

A few of my students have been working through L10 and it seems that frequently they need to refresh the page to get it to accept the changes that will allow them to move forward.

It could be that there are tons of Ss on Unit 5 at the moment, or it could be a lag between our fire walls. Not sure.

My students have not reported anything of this sort. Please click on “Report Bug” on the drop down menu in the top right corner at the level where this is happening. You could also write to support@code.org. I don’t know if it is a bug, but code.org could look into it.
