Block Templates not saving

I'm having an issue the last several days of not being able to copy and save template blocks to re-use, which is an issue for formatting and sharing information between courses. I can add the blocks to a new template as usual but when I save, even after I get a success message, when I go back into the templates screen and try to add the new block template, it shows that it is not loaded and processing. It seems to time out. 

 I am seeing this on multiple computers with different block types, even just saving a knowledge check. 

Is anyone else seeing this issue or have a solution?
