I'm playing a game as the Yor, and I got the random event where the Jagged Knife minor race forms from 24 cities taken from other races. 4 of those were taken from me, and it also said the Jagged Knife get every technology owned by every race it takes a city from. What's weird is that when I took my cities back, loads of planetary improvements were missing, as though they'd been deleted because the new race couldn't use them. Surely this shouldn't happen if they've been given all my techs? So not only have they become an incredibly weak opponent (because of all the improvements lost, at the least), I also have to rebuild all the improvements when I take back the planets. If it's relevant, you might like to note that I did have it set to have the highest possible number of minor races (8, that is) when the Jagged Knife were created. I think all 8 of those original minor races were still in play, too.
So I email the save and debug.err to [email protected] with a link to this post in the email then? Will do.
Also, after noticing that this was a bug I alt+tabbed out of the game to look on the forums, and when I tried to switch back to the game it seemed to hang (that is, instead of staying black but being able to see the cursor until it loaded, it just went totally black). That doesn't usually happen, but that should explain the bit at the end of the debug.err file where it looks like an actual error occurred.
One more thing: this is in Twilight of the Arnor. I have all the expansion packs. I didn't see the post saying that should go in Beta Reports, though that does seem very odd. Maybe this should be moved.
