Expected Behavior

Not to crash? (I'm not sure what to write)

Actual Behavior

Game loads up and boots into a world with no issues, It is once EMI (& TooManyRecipeViewers) is in its loading phase that the game crashes.

Cannot invoke "net.minecraft.resources.ResourceLocation.equals(Object)" because the return value of "net.silentchaos512.gear.gear.material.MaterialInstance.getId()" is null

Not sure if it will help or not, but did a test on the same world, just lowered Silent Gear to the .26 version.

Steps to Reproduce the Problem

This may be similar to #827 , but since there was no logs I wasn't 100% sure if I should tag on or not. Didn't want to tag in if it happened to be different and make a mess :)

Same idea though, updating from an older version to 4.0.27 on the same world crashes.

Looking at your log, it seems like the attempted fix I made for #826 was a dud. I'll have to try something else for that one.

Just adding some info:
Same MC version, no MEI though, only JEI. Only got the same error when I moused-over a material. Not sure which material though, came here to report before trying again.
