How long does a warning last?

[A Suitable Boy]

How long does a warning last? I read in the manual that it should last for 10 years - but that have been exceeded by far in my game now (IN, vanilla patch 3.1.) . I.e. France warning my poor dutch guys.
Am I missing something here?

IIRC it lasts until you have a war.

Thanks... and that is really bad... I share a border with a very blobby France who have warned me...

Used to be 20 years?

I think 20 years has passed too...
The only way out it seems, is to give military access to France and then start a war (vs someone else).
Or?

EDIT: No it worked out anyway! Apparently it is 20 years (or another number). Suddenly the warning was lifted. Good for me... now the only problem is that the blobby France is also HRE...
