Hi everyone,

in Moreaus Laboratory I can´t shoot the stones on the wall in order to open the last door. Even when I hit the
stone nothing happens.
Has anybody had the same problem?
Would be glad for some help!

Same here, I shoot the stones and nothing happens...

There is another thread by member Zoukon about this issue. Though I just have posted in there because I found a workaround solution to the problem, I simply repeat it here as well:

Upon entering the room with the switches my first thought was to use Aard on the pressure plates. Examining the bars on the door makes Geralt remark about hitting the switches with his crossbow - but they outright refuse to get activated this way. Aard on the other hand does the trick. Unfortunately the fourth switch is across a chasm, out of reach! To activate that one you just need to climb the small pillar next to the barred door and use Aard from there. I mean the pillar that is part of the broken railing close to the chasm.

Thanx, it worked with your Aard trick, but they should fix this annoying bug...

Just been there, used split bolts for the pressure plates, worked like a charm.

One thought: maybe it matters what crossbow you use: at (behind) the entrance there is a crossbow to be found.
Nothing special, but - devs sometimes are weird enough to implement a seemingly needless thing (needless because most every player wil have her/his crossbow by now).

had the same problem with the crossbow.
as others have said Aard for the 3 nearest you and for the fourth I just used a dancing star bomb and that worked well. I think grapeshot should work as well.
