Version Info

Minecraft 1.21
Fabric Loader 0.16.0 (and 0.16.3)
Fabric API 0.100.7 (and 0.102.0)
Lithium 0.12.7 (and 0.13.0) for MC 1.21
Nature Arise 0.9.1 (and 0.9.2) for MC 1.21

Reproduction Steps

Trying to open the creative inventory with both Lithium 0.12.7 and Nature Arise 0.9.1 together causes the game to crash to desktop. Upgrading Lithium to 0.13.0 (which was necessary after updating Fabric to 0.16.3 and Fabric API to 0.102.0) and Nature Arise to 0.9.2, the game no longer crashes, but still freezes and has to be forcibly closed.

The 0.13.0 issue does not look like it is related to lithium. Can/Did you test that version without lithium?

The 0.12.7 issue also looks like it is unrelated to lithium

The 0.13.0 issue does not look like it is related to lithium. Can/Did you test that version without lithium?

I did do separate tests with Lithium alone and with Nature Arise alone, and the game didn't crash/freeze in any of those tests.

Out of curiosity, what did you see in the crash report that tells you they may not be related?

In the crash report there is nothing that hints at lithium being a cause. The exceptions are thrown in code that lithium doesn't touch at all

Well it's definitely caused by Lithium and Nature Arise both being installed, so that's incredibly weird.

Nature's arise isn't class loading their blocks class at all, which from the looks means that by the time the creative tab event runs it's blocks can possibly not be registered/the registries could be frozen

My best guess is that you can try disabling the nbt mixin:

Add the line mixin.alloc.nbt=false to the lithium.properties file in the config directory in the .minecraft folder

Ok, gonna maybe sound dumb for a second, but would it change anything if there are spaces before and after the = ?

I never tested it with spaces, so I don't know

When you say "creative tab event" are you referring to some feature of Lithium? Or just, is there something that Lithium does in relation to the Creative Tab?

No it's a fabric api provided event to add entries to creative mode tabs

Add the line mixin.alloc.nbt=false to the lithium.properties file in the config directory in the .minecraft folder

Oh, thanks! I will try that, and I'll let you know how it goes.

I tried adding that to the lithium.properties file, and now when I access the Creative Inventory, I get this crash:

• Crash Report: https://mclo.gs/1tornV3
• Latest.log: https://mclo.gs/Cd1YTgU

That didn't make any difference then

I never tested it with spaces, so I don't know

Yeah, spaces didn't change anything. Also, if I'm reading that last crash report correctly, Nature Arise is trying to add an empty stack of something but I don't know what.
