I set a barrel between a yellow bush and pine tree. I can see it, I can run into it. But I can not interact with it. If I hit tab while looking at it and standing by it, it does not show up in the nearby window.
When I lay down (z) I notice the barrel is floating a foot or so off the ground. I can crawl under it, and if I stand up under it and hit select I can grab it. I am only offered the 'take' option for a brief second.
I was able to reposition the barrel between the trees and it worked fine.
