About this Mod
Lost Cities Squared

Hello and welcome to Strubium steals code from people to make an old mod slightly better
(Forked from: Lost Cities Render Fix)
(Original Mod: The Lost Cities)

Changes (See changelog.md)
- TileEntitys now get special treatment and aren't placed as normal blocks. (Not my work, this is the power of Burchard36)
- New "nospawner" profile. Generates buildings with loot, but without mod spawners.
- New "geopol" profile. Generate cities with the power of GeoPol!
- Tweeks to the "onlycity" profile. Railways + Highways.
- Un-privated all the hidden "base" profies.
- Removed the water that generates inside buildings
- Stopped using dungeon loot in citys.
Future Plans
- A palette that uses MWC Props
- A config system for city loot as 1.12.2 doesnt support datapacks
- Remastered Chisel profile (It will look nicer)
Really Far in the Future Plans
- Investigate the memory leak (https://github.com/McJtyMods/LostCities/issues/251)
- City Zoneing (Downtown, suburbs , etc) (https://github.com/McJtyMods/LostCities/issues/556)
