I've been playing like this for a while, and then I thought maybe someone else would have fun playing with this mod too.
The mod simply increases the amount of building slots provided by upgraded ancillaries.
Default: 4 -> 6 -> 8 -> 10 -> 12
New: 4 -> 8 -> 12 -> 18 -> 24
Before you could have 240 building slots with 20 reinforced ancillaries. With this mod, you'll have 480 building slots. As simple as that.

Installation: open the Core.jar file in the game directory (Steam/steamapps/common/Rise to Ruins in case you're using steam) with any archive manager, go to /rtr/objects/buildings and replace Ancillary.class file with downloaded one.
