Each WilderCraft season is a completely new map seed, reset inventory, and a new experience for most players. Often we develop new custom code and plugins at the start of the new season so there are differences in gameplay season-to-season as well.
Seasons last 6-9+ months
Season resets occur when new Minecraft map generation features would cause us to reset
Map seed, all inventory, donation item purchases and vote rewards are reset
All ranks and infinite home donations and vote counts are retained each season (in past seasons this was reset because redbau didn't save this to a database, sorry past season friends!)
Resets are fun! Everyone loves to explore and build. See you next season.
