Increased income from thievery buildings to offset the fact they reduce parent settlement income before giving it to you (so if a settlement was generating 500 gold, Ratkin Mafia it would reduce it to 250 before giving you half of that, i.e. 125). Now it giveth what it taketh away.

Known issue: the projected income on the tooltip does not take into account projected income reduction from the same building. So before you build it, it looks way better than it actually is.

• Can now recruit chaff infantry from the Warrens building chain.
  
  
• Warrens now increase casualty replenishment for your entire army instead of just characters, and from Tier 3+ also enable replenishment in neutral and hostile territory. This is a pretty huge bonus, so the strength of all other effects of the Warrens building chain (amount of replenishment, campaign movement range, Leadership when attacking, number of additional uses of Menace Below) has been reduced to compensate.
  
  
• Strongholds now grant +1 global recruitment capacity at T5. Sack bonus reduced from +200% at T5 to +50%/+100% at T4/T5 - now that Undercities are nearly risk-free, triple sack value is a bit much.
  
  
• All Food-producing Undercity buildings steal that Food from parent settlements (this only affects Skaven factions). Warrens and Stronghold buildings also drain 1 Food from the parent settlement owner.
  
  
• Assassination buildings now have 3 ranks instead of 2; tier 3 building reduces Discoverability by 60.
  
  
• Thieving buildings now cost 1 food for all tiers, so you aren't penalised for upgrading it. Raiding Camp income stolen from local settlement increased from 10% to 20%, and also denies food-based resources from multiple factions (Skaven, Ogre Kingdoms and Bretonnia are all affected). Both buildings also reduce the parent settlement's income by the amount you gain (they're stealing it, after all).
  
  
• Discoverability of Raiding Camp and Ratkin Mafia reduced to 60.
  
  
• Thieving, Raiding Camp, and Subterranean Strip Mine buildings build cheaper and faster than before. Cost of The Vermintide significantly reduced (build time remains the same, however).
