Gwani horn not breaking ice walls

[B.]

I have submitted a save game and I noticed someone else is having same problems.

I have the gwani horn and am trying to free Gwenno.

The horn causes an explosion on the icewall but the wall remains unbroken.

Interestingly ice blocks in range are broken exposing gwani bodies

I'm using may 3/08 snapshot, SI fixes, and avatarpack.

Okay, fixed just now, so you should see it in the snapshot in a day or two. There was also another bug, where the bodies would appear on top of the ice blocks, but the blocks themselves weren't destroyed.
