This patch is related to bugs related to save/load and memory leaks that occur when playing games.
Previously, when an chunk was loaded, the chunk remained. So as more and more chunk were loaded, the memory load became more severe and the CPU also caused the load.
So, we compressed this part in real time, saved it, and changed it to reload.
And I also worked on Save/Load. Now, we have fixed the "bugs where the walls and floors are properly brought in, but the furniture disappears."
This bug is fatal, so I took care of it first, and while fixing the rest of the bugs, I will work on improving the initial playing guide and UI.
