Bug/Issue Loot drops out of bounds?

So I killed a special slime and it seemed to drop this green sock thing. Unfortunately it's stuck on the wall and I can't reach it. Perhaps unintended?

 

Chopping trees or doing other things that drop items near the edge can result you losing those drops.

 

Steam Version
Mine (not sure if this specific room/tile)

Slime dropped an item, in this case a weapon, straight upwards. It landed in the wall and is not able to be picked up. I do not know if this can happen on any mine tileset or just this specefic one.

Here is a screenshot of what happened. I wanted to include enough of the room to identify it if needed. This looks weird in my preview so I can edit the link to just a url to imgur instead of embedding the imgur link in the post.

*EDIT* Yup, the preview worked but the post broke the image. Here is the direct one!

 

So I was chopping a tree and noticed some of the stuff fell out of bounds. So I did it again to get these two pictures.
