I know about desperate measure module. I use it.
I would know if it activates when the their energy bar fills up, but it doesn't.
The shields were down and the energy bar was empty.
No armor amp because the corvette had medium cloak. That's the only way it was able to sneak up on me. AFAIK corvettes can't have both cloak and armor amp abilities at the same time.
However, there is a bug that someone reported where the dreadnought had armor amp but was still able to warp. I'm wondering if the corvette was able to have a cloak and activate that armor amp also.
I initially thought I was lagging and the server did not update the real location to my client side. It happened a second time. I just chalked it up to a really weird and suspicious coincidence.
Then I see this thread and people with similar experiences so I dropped my comment in.
Thanks for the tip about Alt + F9.
