I have noticed, during a rare stint as granger the other day, that there is a basic flaw with deconstruction for aliens, especially of forward bases.
Suppose you have a forward base with an

and two

's - you mark all of them for deconstruction (as demanded by the ebb and flow of the match). However! Once you begin to use those bp's, the

may go down first and the two
marked 
's instantly self destruct, thus losing their build-points. This should be fixed. They
were marked, after all. Why should they destruct? Human

's don't die the moment the

goes down!
So...if buildables that are
marked lose their

due to reconstruction, they should not explode and forfeit their build-points.
If you want to see a quick example of this, log into a fresh tremor default map. Now mark the

and

that are by the door
opposite the big window. Now, go move the

to beneath the steps or wherever. The two marked buildables
should destruct.
This doesn't happen to humans.
It shouldn't happen to aliens!
