Puft False Confinement Bug

I built this Slime Cube and the Pufts always claim they become falsely Confined. I then have to Deconstruct the building to find which one they are stuck in. For some reason their pathing goes farther then their actual movement or hit box causing them to become stuck. In the picture below this Puft after I destroyed everything around it still claims its Confined. I'm going to see if a reload solves the problem.

The only time a Puft should state its Confined is when it can't find a path in any direction from the current tile its in.
