Waiting for a AI core is killing me.

I understand that until recently, AI cores would show up in regular trading from time to time, and I'm wishing that was still the case. As it is now, I have everything set up, I have for in-game years, just waiting for that AI Core mission to come up and it never does.

If you're on Unstable 1.0, it's possible to pay a friendly faction, and they'll spawn an AI core Item Stash somewhere nearby. You just need the multi-communicator (or whatever it's called) and some silver near your trade beacon.

If you're on Beta 18...I have no idea. I'm guessing there wasn't one in your Ancient Danger room?

The only times I've ever gotten AI cores were from destroying psychic ships. I've had traders that had them, but very rarely and very expensive.

edit: the above goes for 0.18

In B18, the AI Persona Core wil appear as an Item Stash quest at some point within the first 5 years. Thereafter, the chance of another quest is really down to RNG and it may be several more years until another such quest appears.
After that and much later, usually in the mid to end game you may find a passing Exotic Trading Ship will have one for trade.
See here how it took me at least 13 years to acquire a second one lol

In v1.0 (nothing is concrete yet and everything is subject to change on an almost daily basis), I have found through having played 20 colonies so far that the Item Stash quest regularly appears at some point within the first 4 years. I have also found the quest appearing again, so perhaps the chance algorithm has been adjusted to provoke a more frequent event or perhaps it was just plain RNG luck ;)
There also appears to be other means of acquiring it. for example, in my current playthrough of v1.0 build 1982, the first Stash quest appears in the 2nd year,

this was followed by a Faction Trade Request in the 3rd year,

I am currently in the 6th year and there have been no further opportunities so far, but I do expect that an Exotic Trading ship will have one later on, as is the case in B18.

Since I knew this change would be a ballache for finishing a game, I procured a couple mods for B18. One brought back the core dropping out a psychic ship when destroyed. Another mod made it possible to craft cores and neurotrainers with later game resources.
