It seems that an object is stuck inside a server or between some rigid geometry. You can try to find the object, or try to dislodge it from wherever it's stuck using an explosion (slam a gas tank on the floor). If you can't find or dislodge the item, you'll just have to deal with it, or if it gets really bad, you can reset objects through the reset menu in the save screen.

Unrelated footnote: Wonderful keyboard, satisfying to hear :)
