This man alien enjoys abducting my plumbots

I have 7 sims in my family. 4 sims are all young adult men, a little boy and 2 plumbots. Recently, I'm trying to complete the logic skill challenge. My 2 young adult guys have been using telescope for finding stars. The alien didn't care my young adult men sims. He abducted my plumbots 3 times so far. It happened all in a week. Is that usual that any aliens abduct only plumbots?

This is the first abduction for her today.

This guy plumbot was abducted 2 times by the exactly same alien guy as the one in thought bubble above my girl plumbot.

I'm excited now how many more times that alien guy will abduct my sims until my 2 guy sims complete Celestial Explorer skill challenge in logic. :D
