Friendly AI stole my outpost!

[Isidorn]

TL:DR An AI I had Defensive Pact with walked into my outpost and captured it.

So, I captured a wonder and placed an outpost next to it to get the wonder. When the outpost was built and I was going to annex the wonder to the outpost, my neighbour, who I had defensive pact with, had placed troops on the outpost so I couldn't do anything.
I was thinking WTF and waited two turns to see what happened. And yes, the oupost changed to that of my neighbour and my troops I had at the outpost were suddenly trespassing! (didn't have open borders active) To make things even more annoying, I had to wait 1 turn to declare war to take the outpost back, as the Defensive pact had to be broken first.

I know the AI cheats, but this was a little bit too obvious.

Did the AI walk on a finished outpost? That should not be possible without declaring war.

But if the outpost was under construction, that sounds a lot like a bug I encountered last month: https://forum.paradoxplaza.com/forum/threads/ai-ends-up-taking-control-of-an-outpost-i-am-building-while-not-at-war.1588147/

I suspect it's not an AI cheat but a bug, and it would work the same for you, if you can spot any AI outposts being built.

As it was just from one turn to the next, the AI must indeed have walked onto the spot before the outpost was finished and then finding itself standing on it when it was finished and somehow got the option to capture it even though they weren't at war with me. So it does sound like it's the same bug,

I know walking onto a spot where an enemy is building an outpost simply cancels the outpost being built. I've never been able to try it with an AI I wasn't at war with.

It is a bug or an oversight. The friendly AI can walk into undefended structures like outpost or province improvements and choose an option to transfer it to itself. I saw people mentioning it a month ago.

Confirm. I have encounted same issue

[rumpelstiltskin]

hmm could be a counter to friendly ai spamming outposts. just have scouts follow their heroes.

[Kerican]

It almost seems deliberate. I have had this happen more times than I can count, the ally unit comes out of now where to sit exactly on the outpost before its constrruced.

If you encounter your neutral/friendly AI taking over or occupying your provinces/outposts etc. without Declaring War, please make a bug report with a save from the turn before the AI did this. We've done a call out for these but very little saves have come in so we haven't had much progress in tracking down why it's doing this.
