I allied with the Unfallen during a single player game and they extended a tendril into the middle of my influence zone and connected up to a system with 4 fully developed planets and ecstatic morale.  I didn't care initially, but then I noticed that it says that they are slowly taking over my system at 2% a turn.  I ignored it for a while until it got close to completing.  There is no option within the diplomacy screen to request them to remove the tendril from my space.  To avoid losing one of my best systems, I positioned some fleets in the connecting system to the tendril heading to my system.  I then left the alliance, with the intention of declaring war to try to keep control of my system.  As soon as I left the alliance though, the system was instantly controlled by the Unfallen.  The hero that I had in the system is now wounded and the fleet that was there doesn't seem to exist anymore?  

So are the Unfallen just really unbalanced and can take over whatever they want (including their ally's systems)... or is this some kind of bug?  

Unfallen are meant to be the peacefull allies of the universe, but, nobody will ally with me because of this in MP. I feel like this tech should do something different for unfallen, like, whatever resources they get, you get also.

Not a bug, I think the Unfallen are great, but need a bit of reworking... try talking about this in game design.

I doubt it's intended. Why would they make the "ally" race the worst person to ally with? THe unfallen get bonuses for allies, but people don't ally you as you can just click one button and have all their stars unless they wipe you out.

Maybe it's intentional. Casting tendrils out onto a system should probably be deemed a pretty hostile action by both players and AI though - it's the Unfallen's version of influence zones. And while the AI don't like your encroaching borders, they also probably shouldn't like tendrils being extended into their systems.

What might be a bug though is that fleet just disappearing. Did the Unfallen take control of that too?
