Good that you're working on the game so constantly still, you have my respect for hanging in there. I loved the bulk crafting, extravagant clothing, nobility progress, the more realistic sandbags and the new quest system (especially more quests on the map and not the caravanning spam of old RimWorld quests) of the Royalty update. I also agreed with the mech/drill rebalance, and I'll see how I feel about the meat delivery nerf in time.
However, what I really didn't like was making the Empire the enemies of the civil factions, maybe a warning if there are no hostiles for them to fight instead (maybe mention that they are neutral to civil factions if they're on the map too)? Fighting the civil factions if often a conscious choice, and the Rim is rife with factions hostile to each other already. Alternatively maybe a toggle in the game setup for whether they're to be hostile to the civil factions or not?
Also, sorry about the derailing, but could we have an update on the rock types that were changed? Specifically if you want to revert the changed rock types on the maps, or if you'll keep them as they became with the recent update? Here's the links to the relevant threads on the Ludeon forums:
1 and 2.
If it helps I can confirm it happened to my saved game too. While the mountain is still granite/sandstone in my safe, the terrain and thus probably any new game started would be marble/sandstone. I want to know what you're going with so I can be on the lookout for the correct seeds for future games. Also I heard something about it influencing deep drilling, but I'm not that far into the game yet.
