Yeah, I've also noticed hybrids being increasingly suicidal. They keep going 1 by 1 into kuplu, a planet of mine with miniforts, mk 1 fort, mk 3 mil command, and a mk. III ff. They go in, look like they're going to attack, then attempt to run away (incidently, Kuplu just got taken out by an exo right before I took the save).
I also had a super hybrid attempt to build a facility on one of my planets, by himself, with over 150 turrets on the planet, twice now. The first time it happened I didn't get anything, but this time I have a screenshot and save.
Astro trains are also randomly going on coffee break. They just stop and sit there for 2 minutes or so before moving on, seemingly at random.
*edit*
The super hybrid runs away almost immediately, but I don't think he should be showing up there to begin with.
