When Dungeons Arise

• Fixed most mobs on Heavenly Challengers - also added extra mobs for extra difficulty.

• Fixed treasure loot tables on Heavenly Challengers.

• A lot of tweaks were done to loot tables. This is not final. Exploration maps were added to certain loot tables to encourage players to visit new structures - these may cause brief lags when opening some chests. This is how vanilla handles exploration maps.

• Added a safecheck so flying structures don't attempt to generate above worldheight.

This update is part of a bigger update we're planning, which will introduce new massive structures.
