Leviathan can attack from inside the Vortex with its tentacles

Just witnessed another bug.

Someone built a Warp Manipulator right near the low right corner.

When Leviathan came, he attacked it with the Vortex.

Leviathan got in there, but kept attacking from inside of the Vortex hole with its long tentacles, while it was supposed to stay isolated from outside world!

So instead of neutralizing it, he made it invincible. Another fix for the next patch.
