BetterLoading aims to improve your game loading experience.
In vanilla RimWorld, once you get past about 50 mods, the process of loading up the game largely consists of staring at a repeating "..." prompt for anywhere up to several minutes.
It's better now than it used to be, but in extreme cases, this can still take up to half an hour. And for that half-hour, you're just staring at that "...".
This mod doesn't improve load times. But what it does do is give you an actually useful loading screen so you can see that something is, in fact, happening.
It also reduces (though doesn't remove, due to technical limitations) the freezing that can be observed towards the end of the loading process.
This mod requires: Harmony.
