Spring RTS Engine

Please explain me why the flow at 5:45 doesn't die:

There is something that a unit can have 0 or NaN health and then it not be killed. I think I read in lobby that it is already fixed or being fixed.

Paralysis disables the unit's update function, by the looks of it bullets are passing through so some collision data isn't correct, possibly something that gets updated regularly but can end up wrong for a frame or two...

So, engine bug?

Highly likely.
