VISIONS OF ENMITY Items konnten nicht aufgehoben werden

Hello, I was in one of the VISIONS OF ENMITY and had the problem that in the last level, that was in my case. Nice memory, top right. In the corner of the chest was all the items that fell behind the chest. I couldn’t pick them up because I couldn’t come around the chest neither from the right nor from the left.
Which certainly shouldn’t be the case.

I apologize if my english is not so good. I use the google translator
