Issue description

EMI is a item and recipe viewer, much like JEI, however when both are installed EMI uses JEI as a backend, for mod compatibility.
When the three mods are installed opening the inventory chrashes the game with the next exception:
java.lang.NullPointerException: Cannot invoke "mekanism.common.lib.attribute.AttributeCache.get()" because the return value of "it.unimi.dsi.fastutil.ints.Int2ObjectMap.computeIfAbsent(int, it.unimi.dsi.fastutil.ints.Int2ObjectFunction)" is null
within the ItemMekaTool.getAttributeModifiers method.

Steps to reproduce

1. Have Mekanism, JEI and EMI installed.
2. Open the game, enter a world.
3. Open the inventory, crash.

have u solved it?

I am not able to reproduce this in 1.20.4, but also does this happen consistently? Given my best guess is that there is some sort of multithreading race condition going on, as that error really shouldn't be possible otherwise.

I just opened a world 2 times after updateng all my mods and it doesn't happen anymore, something may have fixed the bug.

I can confirm that this issue still exists but it's just inconsistent. Try reloading the game and opening the inventory until it crashes.

My guess is this no longer should be an issue given we now have native EMI compat, can you confirm if it still happens on the latest version?

Does not seem to happen.
Just to be sure JEI compat is disabled when EMI is present right?
Also is the 1.20.1 branch no longer being updated?

Experiencing the same issue here.

Hey. I solved this issue by deleting what i think was inventory management. The mod that lets u sort ur inventory by the click of a button. After i deleted it, it hasn’t happened again

Interesting. I'll give it a try when I have a chance.
