Hello,
I have the problem that our title block behaves strange. When inserted, it doesn't show up, because the title block layer is deactivated (why ever). Additionally the title block does not scale properly to my drawing. 
We had the case that two persons are working on the same file. Not parallel, of course.
What can be the reason for this?

Second image: Layer deactivated
Third image: Title Block not scaled correctly
