* Pre-patch preparations
* Update magic values
* Check formatting characters directly rather than string compare
"Brown".StartsWith("\u000e")
>true
what
let's be paranoid here, because .NET Core behaves differently from .NET framework.
* Update FileHashRevision.cs
Postbox with the massive decrease in size; likely the same mutation caused the other massive decreases.
* Dump item names
* Update flag definitions
* Update item info
* Add feathers to bug list
Might remove later.
* Update RecipeList.cs
* Update ItemRemakeUtil.cs
* Update stack details
* Update offsets
* Update MainSaveOffsets17.cs
* Update GameLists.cs
