Anyone else see this before?
I've seen it too! Especially after you've upgraded to the Disintegration Assault level (1rst lvl). Then it only attacks at the Pulse gun range, but rarely to the shorter Disintegration range.
It is easily replicated, but it doesn't always do this. I don't know why it sometimes doesn't move into range.
The SB will wipe out everything in the Grav well, but leave 1 extractor untouched! Later when I've move the SB around, and have dealt a small amount of damage to it, it will turn around and come back to destroy the previously untouched extractor. I now always issue move orders to my SB, so that it moves across all structures and quickly destroys everything in its path.
In this replay, a couple different times, the SB will move to attack the frig factory (and scouts & constructors there), but stops short of the disintegrators range, therefore taking much too long to kill them.
Also, I think Debris Vortex is bugged!? I've never seen it do anything! No repair, no nothing. What does it do?
And the 2nd level of Frontal Deflector Sheild blocks 200% of damage rather than 100%?! How can it block more than 100%?
