I get crashes when using Rubidium and opening JEI.
As soon as I click on next page and previous page in JEI, the game immediately crashes.

The crash splash screen says:

The game crashed whilst rendering item Error: java.lang.NullPointerException: Cannot invoke "it.unimi.dsi.fastutil.objects.Object2IntMap.getInt(Object)" because "this.uniformCache" is null

Here is the crash report:

CurseForge v0.234.3.1
Minecraft v1.20.1
Forge v47.1.43
Rubidium v0.7.0a

🤷‍♀️

Update Rubidium to 0.7.1

Works like a charm thank you. 🤓👍
