Nah, none at all. Total vanilla server.
I am running my client side clean also. I can work around it. I would just have to have someone pick up the shelf for me and I would have to place them. Once I place them, it fixes the bug but not until then. There was something else that I found that did this exact same thing in the same manner. It happened to me a couple months back originally with iron shelves but once I placed a spare I had, it fixed it. It would highlight one side but not the other (only the side that I was able to pick up when half of the shelf broke).
It seems odd that a 2 tile item would have half of it destroy when picking up. It's as though it makes 2 checks, one for each tile. When one breaks, that's the one that will no longer highlight.
For example:
- Tile 1 and Tile 2. Tile 1 breaks but Tile 2 doesn't. When highlighting a similar item to pick up, it will show Tile 2 red but when highlighting over tile 1, it just shifts Tile 2 to the left to cover Tile 1, again highlighted red.
The item doesn't even appear in the window. The only thing that will show up in an info window is the floor tile below it. I've even shifter (R) to see if I could select the shelf and it acts as though it's not there. This is a totally different area but same shelf. (Or I should say Magazine rack)
The only thing I have not done was reinstall the game to see if that would fix it. Still, even if I did this, it would likely occur again if I failed on picking up a 2 tiled item. Doesn't have this issue on a 1 tile item.
