First of all Added support for most mods which have custom areas in it 

Mods which are supported:

NTTE: NT:TE by Yokin, THX (itch.io) 

Hardmode: HARD MODE by blaac (itch.io)

Hive: The Hive by Sunny (itch.io)

Secret Areas: 

Undergrowth: The Undergrowth by attfooy (itch.io)

For them all i added 7 new spawn pools (most of custom areas will use already existing one) 

Fixed IDPD Chests in Snow Town 

Added Chest replaces for some custom areas 

Crown guardian spawn instead of proto statue after visiting 3 vaults now supports some custom areas too (Coast, Trench and Hive) 

Now you can easily add your own things for custom areas
