I noticed since #176 a weird change in Warbot behaviour.
They mostly seem not up to a fight, just walking away when you shoot them.
Seldom, they start to come closer, but mostly they just wander around.

Also, most of the time they just ignore you.
A couple of times I aggroed a bot and then could run around his legs without him shooting me once.
Then, after a few minutes, they change behaviour and start invisible shooting, as in you can't see them shoot and they don't change in shooting pose.

This goes for their beams as for their rockets.
I also tried this in various sectors, so it's not a bugged zone.
