[1.16.5] Replaced vanilla block missing from default creative tab [RESOLVED]

[Soft-fur dragon]

I followed recommendations in this thread and finally got my new cauldron block in game. However, now it's missing from its default creative tab (brewing).
I also added TileEntity to my block and now world stopped loading at all, if it have at least one cauldron tile entity in it ☠️

you need to register a BlockItem for the block, and set it's group to be the Brewing ItemGroup

[Soft-fur dragon]

Well, that was pretty obvious, but thanks
First problem is solved.
However, world is still being broken. This is what I see when I'm trying to open it. The game freezes in this state

[kiou.23]

could you post more of the code (maybe a git repo)? I don't see anything wrong with the code you shared

[Soft-fur dragon]

Just uploaded in on GitHub

[Soft-fur dragon]

Ok, I found it. Inside my cauldron TileEntity you can see onLoad function. Inside it I call UpdateHeat function, which calls world.getBlockState. I tried to debug this code and it seems like it freezes on trying to load chunk to get BlockState on that position. Bug? Or is there another way to get block data on world startup

[Draco18s]

Don't. Because it happens during chunk load, the chunk hasn't loaded yet, so it pauses the load to fetch the chunk you're referencing, which is the chunk that contains the cauldron which is currently paused waiting for it to finish loading.

Do that check in an update tick.

[Soft-fur dragon]

Got it, thanks for clarification
