The long awaited Mountain Bug fix: Armies will no longer be able to spawn in mountain terrain, which prevents them from moving on the campaign map

Other changes:

• Undercity buildings now have a list of units they can spawn, each unit has a weight, if the buildings collectively bring 19+ units, only the best are chosen, this leads to strong and diverse armies representative of their undercities
  
• When a settlement was taken by the player or ai from a skaven faction, there was a 50% chance that the city would spawn an undercity belonging to the previous owner beneath it. This undercity now generates a Warren based on the previous city level
  
• Warrens and Strongholds now give income, they're no longer useless. They also have the strongest garrisons, so they're good to build in undercities you don't mind being discovered

Fixed a bug caused by CA's horrendous changes they made to the keys skaven weapon teams building chain

Also fixed a bug on my end that would cause the undercity building list to fail to convert to their normal city counterparts.

Fixed a commented out line of code that disabled the undercity razing mechanic

Cleaned up some of the code, removed the possibility of infinite loop that resulted from a CA interface failure.

Added Ikit's special warp lab building to the building table that was causing crashes

Fixed a potential crash that could occur with invalid buildings, the above should fix this but I'm being extra safe.

Script will now abort the undercity battle if it can't find any valid spawn points for the armies, this is to prevent crashes and freezes

Made a few tables global to allow other mods to add/edit the unit and building entries, as well as add their own entries

Fixed a typo that could have potentially caused crashes for coastal undercities occupying the ruins above

Added a new mechanic: 50% chance of spawning an undercity when a skaven faction loses a settlement to another faction

Removed a part of the script that added skaven to the old world. I like the idea but it could cause incompatibilities

Initial Release
