Seriously Larian? "Halfred's Note"

[Loopan]

To avoid a spoiler I simply say there is a place I have to reach for a Questline and on the altar there should be "Halfred's Note". For a reason only Larian could explain is that note destroyable. And in front of the altar are two nasty creatures. I obviously destroied the note with my first Lightning spell. I learned about this circumstance of course not at that time. I had to read about this in the internet because I couldn't go on in that particular quest, because I didn't know about that note! To my luck I learned about that BS after an hour or so. So I don't have to backtrack a whole lot. But the fight with these creatures wasn't a walk in the park so I have to wait one or two days until I feel like it again!

Common Larian, thats just bad gameplay, if one blast can corrupt an entire questline and the game doesn't even tell!

You can still do the quest, nothing is ruined. Next stop is the Mason's Guild. Quest will update when you go to the right area.

This is not a 'critical' quest item. Just a bit of flavor and lore. :)
