I think I deactivated my own problem...

[lalalala]

I just tried uploading a problem and I accidentally clicked "add to sandbox" so I went to the sandbox and unchecked it. I then found it in the deactivated section and it said to check the history to see why it was deactivated and I only see my own edits. How do I fix this or was it actually deactivated by someone else?

You may have removed the tick in the 'Problem is active on this site' box as well as the sandpit one.
I put them both back so it is in your sandpit again.

The problem could do with an introduction and a lot more variations, esp. to refute reasonable looking wrong moves.
It is a lot of work, but that is what makes these stand out from the book version where maybe just one or two wrong variations get shown.
