AI surrendering

[akatung]

Hi everyone.
So I just bought Stellaris and I'm playing my first game. I declared my first war and I set two wargoals (liberating two different planets). I was winning when suddenly the AI surrendered but only gave me one of the two wargoals. How can I avoid this? I didn't want them to surrender yet if I didn't occupy both planets! It was quite annoying

If it's an incomplete surrender (not offering all of your wargoals) you can choose not to accept.

I'm quite sure that it just happened and I didn't accept anything... But I guess I missclicked really quickly or something and accepted without noticing. It certainly didn't make any sense. Thanks for the answer!

Another possibility would be that the AI was in another war at the same time, and whoever that enemy was took the other planet that you were going for - so the AI surrendered everything that was left of your wargoals.
