Hi Yah.
I'm an Admin with Sharkbitefischer on Rosalia.
Found a prob with the script when removing the stock ladders.
-------
In Creative Mode as Admin......
Pressed F and held to remove ladder.
Chat window confirmed ladder - (ID number) removed
Ladder NOT removed.

Ladder removed.

In other words you have to got through the process twice, for the routine to work correctly and remove the ladder.
UPDATE: Its also affecting destroying the ladder with a pick axe. So the problem is global to all activities performed on the object.
Thanks Yah. :DD
