 Improved areas
 ====
 - Most barriers to travel across the region have been removed, allowing for almost fully open world gameplay. To encourage this, Gym Leaders now have level scaling, giving more consistent challenge across the game. 
+- Cinnabar Lab's Trade Room now features the Trader, who will evolve trade-evolving Pokemon for you!
 - Rock Tunnel has a more workable map, now being easier to go through and having new areas to explore. Includes a way to get renewable fossils, items, and other interesting bits and pieces. Overall, it makes Flash much more rewarding to bring, showing you where the items and content are instead of being an inconvenience. 
 - Diglett's Cave has a more detailed map with Onix, Wiglett, and Wugtrio also appearing!
 - Route 25 has been given a facelift, adding Bill's Lighthouse!
 - The Route 5-6 underground path contains a shortcut to Celadon City. 
 	- This allows you to skip Route 9 and Rock Tunnel, making them optional areas and opening up central Kanto.
 - Cinnabar Island is a lot bigger, and has a new location added to it. The mansion seems different too...
-- Cinnabar Lab's trade room features an NPC who'll trade you back your Pokemon for trade evolutions!
 - Pokemon Tower was shortened, being less intensive and adding room for more maps.
 - Silph Co's pathing was completely overhauled to make navigating it less tedious.
 - Viridian Gym now has a new area once you make Giovanni leave.
