Bookmark from mine.cs doesn't worked - in Sanderling - in a game

In old version worked

As I understand, you solved the problem for now.

Let me know if you are seeing this problem again.

That is Actuality problem on v16.04.12, but bookmark worked at v16.03.09

When you upload the script you used to compare v16.04.12 to v16.03.09, I will take a look at it.
