That's interesting, depending on the time between checking the notams and approaching the restricted area.
If it was a short time then I think it would constitute a hazard alert and ATC would be obliged to make appropriate broadcasts and be alert for those, such as you, who were operating on obsolete info.
If it was longer, then you should check again, as you did.
Some deactivation notams that I have seen in the past, point out that activation, during the deactivation period, is an option but I can't find one that says that now. Might be in the AIP or ERSA.
