3946	NPE - While undoing terracer action	Ldp	zerebubuth@…	"Select building outline, make a terrace (I had 4-10 even), and associate with a nearby street. The action is performed and new building outlines are created. Undo the terrace action, and get an NPE (see below).

Now, if I make the terrace, reverse it, and then undo those 2 actions, it works ok.
