LostCities 1.21-8.3.8


   - Implement a better caching system which keeps track of how long ago something was last accessed. This should improve performance
   - Extended the world settings with four new options: vinewest, vineeast, vinesouth, and vinenorth. With these you can change the vines that are used for the buildings
   - Fixed a potential infinite loop with bridges in combination with the new caching system
   - TqLxQuanZ fixed single player forceSpawnParts having race condition not working properly on setting world spawn during single player.
   - TqLxQuanZ fixed an issue where player reconnecting to server might get teleports to the world spawn, despite having a bed setup.
   - TqLxQuanZ fixed single player forceSpawnParts having race condition not working properly on setting world spawn during single player.
   - Fixed a problem with the lostcities-server 'selectedProfile' config option being ignored

   - Fixed part2 generation issues
   - Fixed rain not properly going into destroyed buildings

LostCities 1.21-8.3.0


   - Fixed lost city loot folder
   - New 'railpartheight6' setting for worldstyle that indicates how high railway parts can be (in multiples of 6)
   - New 'optimizedHeightmap' config option to use a more optimized way to calculate the heightmap. This is disabled by default
   - New 'heightSampleSize' config option to control the size of the heightmap sample. This is used to calculate the heightmap for cities. By default this is 1 which means every chunk
   - TqLxQuanZ added four new city levels
   - Changed how park generation works, now there's a config to determine if park should spawn when the neighbouring street must more than a certain amount.
   - Added optional building floors override Profile/Citystyle floor settings. (Use "overrideFloors": true in building definition)
   - Added ParkChance/FountainChance/AvoidFoliage/ParkBorder/ParkElevation/CorridorChance/ParkStreetThreshold support for CityStyle override. Meaning each city style can have different chance now and settings on those now!
   - Fixed ParkChance not working at all, it scales with total neighbour street condition + current chunk's park chance.
   - Cleaned up unused/outdated profile settings.
   - TqLxQuanZ added an option to use multibuilding top left corner level instead of average level for multibuildings
   - Improved the flattening algorithm
