Bug report: Trophy bug

[kilzone]

Today, (it just happened) I was dragging my favourite trophy (the bonebeast trophy ) around in my house. I placed it on the following wall (see picture and now it dissappeared? I couldn't get it off, it's just gone!
I suppose this is a bug, or is there anything I'm doing wrong?

Greetings,

Gaara

It's a missing sqm from their mapeditor, they need to fill it...

Btw, tell what house that is, easier for Hani maybe to check

Ah, that's the cause! It's the house Oskahl I h (Ankrahmun).The building to the northleft of the ship. Very easy to find .

Edit: I killed ribstride and obtained another bonebeast trophy
