Thank you for the report! Ugh, this is why stabilization takes some in-game time, so you can't just jump through immediately and leave. I'll make a note to see if I can make it more heavy-handed after that time runs out, or perhaps make the rest of the tutorial optional from that point on.
You can fix your save, I think, by downloading the Console Commands mod (and LazyLib) here:
https://fractalsoftworks.com/forum/index.php?topic=4106.0Then opening the console and running this:
RunCode Global.getSector().getMemoryWithoutUpdate().unset("$tutorialRespawn");
And this:
AddAbility "distress_call"
That should make the game think the tutorial is finished, and give you the Distress Call ability, which you get when you go back to Ancyra (which you didn't). The actual tutorial mission will remain unfinished, but shouldn't hurt anything.
