CityApartments is a script for Skript plugin. I wrote it for my server but I decided to release it. My script allows you to buy homes with signs.
It's in very early stage so please report any bugs.
REQUIRED PLUGINS: WORLDEDIT, WORLDGUARD, PERMISSIONSEX, SKRIPT
Installation: Drop region.sk and CAlangEN.yml or CAlangPL.yml to plugins/Skript/scripts.
