Enemy robot can become stuck while building something

By standing in this location, Blupi can prevent the Enemy robot from finishing its building animation. The building will continue, and the robot gets stuck when the construction becomes solid.

This bug appears only when the speed is x2. With the normal speed, the robot moves (after the build) when Blupi move too

It seems unstable...

Here are examples of the Robot getting stuck in normal missions.
x2 speed makes no difference, as long as you wait several seconds after the construction is finished.

I've found that this can also happen to a Blupi, given the right conditions.
