I agree with you.

In my opinion is was just convinient to make Merlin blind towards those magical objects. This wasn't the first time that consistency and logic had to make way to serve the plotlines. I haven't got a problem with minor plotholes or mistakes but I think it's inappropriate when such things happen too often and most of all when it happens to tell a story that doesn't make sense in connection to previous epsiodes. Merlin can either sense magical objects or he can't. If there were special circumstances and reasons why he couldn't in some cases, they should have given a logical and credible explanation.
