Hi again!
I've now finished 3 or 4 games using your Patchwork mod. Game has been very stable, ctds are extremely rare. I've only played medium or large maps and most opponents in a game I've had was 11. That game lasted for almost 22 hours, and was less than 200 turns, mainly because I'm a completionist and I MUST search every damn corner of the map or I won't let myself get any rest. Come to think of it, I have never played a LH game which lasted more than 200 turns... Anyway, hardest difficulty so far, that I've completed, was hard/hard and it seems relatively easy. Instead of reporting bugs, I'm just gonna go ahead and post some observations of those games. Hope it helps.
- So far, after you removed the excessive cheating resource bonus of the AI, I have never felt really threatened by the AI factions. Maybe it's the tactics I use, but after my herostack of doom reaches about level 10, I can mow down everything on my path. Even conquering cities is relatively easy. Things are much better than in vanilla LH, but still, every opposing factions feels just a hindrance, not a serious enemy.
- AI sometimes conquers cities back, like the ones I have not stationed units in. That said, I've never seen an AI attack my city and lose. Seems like it takes no chances and only attacks weak defended cities with overpowering force... And then I move my real armystack in and decimate the perpetrator.
- AI sovereigns I encounter are always either commanders or guardians. Only once, in one game since your last update, I have seen Relias pick the assassin profession. No mages or warriors so far. And I've slain about 40 sovereigns. This is rather boring, as for example, Procipinee or Ceresa are outright bad as anything other than a mage.
- AI still (this "feature" is in vanilla too) spends shitload of money on leather greaves and carries multiples of those. Also, while they usually carry a lot of equipment, they still seem to prefer bows as weapons. Guardian with a balanced short bow is pretty sad in my opinion.
- AI prefers archer units to the extreme.
- I wish there were more heroes to choose from, when amassing fame. Choices feel so limited at times. Also, the premium heroes with their dragon mounts are, to me, way overpowered and geared to max leaving no room for improvement. That said, many level 9 heroes also carry superb gear compared to anything I have on my already existent heroes. I guess this is a matter of taste really, but I still feel I never have to buy any gear for my heroes from shops to be successful.
- When creating a custom sovereign, there is no reason to pick anything but Bonesplitter as your mount, if you are speccing for a mount. It costs the same as everything else, and is easily the best one.
- I once saw Markin kill Delin, Pyre of Man. Good for Him! Right after that I defeated and enslaved the victorious sovereign. 
- The Dead are always the underdogs, which seems to be yet another feature from the original game.
- AI can kill dragons rather early in the game, if it wants. I wouldn't dare to try before packing some punch, as I know the firebreathing is an unmatched weapon until later stages. On the other hand, I have sometimes tried and auto resolve occasionally ends in my favor against dragon. This must be the case in vanilla LH too.
- It must be very hard to create a balanced AI for this game. In my games, I rarely see AI factions fighting each other unless I bribe them to. They still DO declare war on each others, occasionally, but combat engagements are scarce. One exception is, that the Dead always get mowed down. I have to point out, that when your mod was giving AI the enormous advantages they did fight each other a lot, and even I was scared to attack an enemy city as I was expecting to lose unless packing some serious heroes or units, which I didn't have as I was so much behind in the tech race. Good times, and the only times where I have been on the verge of defeat. 
- I haven't seen a Hoarder Spider lair for ages... Come to think of it, not since I downloaded the official DLC a few weeks back. Hell Knight lairs, on the other hand, are abundant though. there must be rarities in the mob selection more than I can think of, as the lairs seem very monotonous nowadays.
- Hardest fight is still the quest for the Ashwake Dragon, because dragon breath is an instant kill on anything not fireprotected... Thrice. And it's still an easy fight when you finally get there. I have attacked a city where there must have been about 18 defending units, and I still killed them all in 2 or 3 turns.
Next game I'm gonna play on expert/expert and after that gonna finally try ridiculous settings. Maybe there will be some resistance then and hopefully I get my ass handed to me for the very first time. 
Overall, even with some balancing issues, your modifications beat the vanilla game hands down... So cheers to you!
