I have been heavily focusing on the overworld thus far, which is obviously where most of the action happens. For the quest I am working on, I needed to create an interior space, and have decided on a way I want to accomplish this. 

Based on a few rules, I can isolate the tiles in each chunk that need their upper layers removed without messing with plants. I made this happen upon interaction with the "door" object, then when the player leaves the new area for the interior space the entire chunk reloads back to its original state (while saving npc and other data). 

Although the entire chunk is unloading and reloading, I did not see any hints of this happening on my laptop. I think if run on very low powered hardware, the player might see a glance of the open air below the tile. 

I think this has solved a big issue for me, and I will use this new method to continue working on the quest I am implementing. I have an idea for the player to go to the past, and this quick unload and reload will also help me do that. 

In other changes, I have optimized the map a bit and have most of the lead up to the climax of the quest written for the grandmother (the NPC that is inside the mound house). I have been planning a bunch of the other areas as well.

Stay tuned!
