Merlin's Beard!

[empty plover]

So I completed....or at least I thought I completed...all of the Merlin Trials. However I didn't get the achievement for completing them all.

I've checked and double checked my map and I'm not seeing any more markers for the trials. Are there maybe some that don't show up on the map? Am I missing something? And has this happened to anyone else?

yeah about that. Get on your broom, fly around the map while casting revelio. Sometimes merlin trials, just like most of the other POIs, does not show up in the map if you have not been near it.
