Underground building, Invisible Walls

[Zenity 736]

Have had an underground building for a while now in a cave close to my deed, (Independence server, deed name is Quicksand).

 

Recently I noticed the walls had disappeared, all but the door.

 

 

This is Unstable client.

 

On Stable it looks like this:

 

 

Cave is about 30 tiles East of deed, I rarely go in there, the building was more of an experiment/test, but only noticed this recently. The walls are still there on unstable, I cannot walk thru them, but they are not there, no other visual glitches are apparent, just the invisible walls.

 

I have tried leaving and re-entering the cave, in case it was related to the invisible ore vein issue which affect cart passengers, entering on foot, cart or horse makes no difference, on unstable the walls are simply invisible.

Already reported.  I get that as well but it's hard to reproduce at will.  http://forum.wurmonline.com/index.php?/topic/145363-40-bug-upper-floors-of-cave-buildings-not-there-unstable/
