Additional Context

Just a server, will wipe my playerdata so its not a big deal, but should be resolved nonetheless

This isn't a bug with Create.

Minecraft will kick you if you have too much data.
When you play modded Minecraft, make sure you don't have too much data in your inventory.

(don't ask me anything about Create. I am not a developer)

yea i realize that, i just assumed that they should do something to make sure the minecart contraption never pushes that limit which is y i put it here

Is there any way to search in NBT Explorer* for that contraption and edit it to get it down to a size that won't boot the player? I unfortunately didn't backup my single player world and now can't get in. I'd rather not start over. If I can find this contraption and edit it, hopefully I can load in and correct it.

I believe where I went wrong was too many chests each with a single block in each cell. I was using that was a way to filter the blocks I would collect (ie double chests of only cobble, dirt, gravel, etc.).

*When I try to search "contraption" in NBTExplorer the program freezes and then crashes. I'm wondering if there's a specific name/value I could query to find a contraption.

Hey ik this is old but here's my weird solutions...

if its in your inventory than just look thorugh ur inventory and there are some tags that you can delete
if its still placed I just found that /kill works well in console (This is on a server, idk if it works on singleplayer)
IDK how helpful this is 🤷

[mcspacecash]

It's not in my inventory, unfortunately. It happened the second I flipped the lever to turn it from a contraption in the world to an entity. I'm assuming that when I did that it turned into a single entity with too many NBT tags. Unfortunately, I believe I would have to find the chunk where that entity is, but I don't know how/where. If I knew what to search for in NBT Explorer and if NBT Explorer wouldn't crash when searching I could probably do that.. :-(

Same thing happened on my server. It would be nice if there was some safeguard against it, such as an error notice and preventing you from creating the entity or picking it up when the NBT is too big. It's very easy to nuke a world unexpectedly.

i made a client side mod that can solve it, and also XLPackets works to solve it (i think). Here is the mod in question https://modrinth.com/mod/create-big-contraptions Would love to see a fix in base Create though!

[LaidBackSloth]

For me, neither CreateBigContraptions nor XLPackets did work, but https://www.curseforge.com/minecraft/mc-mods/packet-fixer did

[PiTheGuy]

Create already has a check that's supposed to prevent this, but it clearly doesn't work every time

Server seemed to have issues after using Create's Item Vault and hooking chests to it. Getting the exact error message above.

not sure if you will find it useful, but I made a mod that fixes this client side, called Create: Big Contraptions. XLPackets I think also fixes this issue

[DereC4]

Happening on my side too; anyone have luck using nbt explorer to fix this?

[IThundxr]

There's a check that prevents this

[Decryptu]

If anyone runs into this NBT allocation error, I created a simple Python tool to help diagnose the issue: minecraft-nbt-depth-checker

It analyzes your level.dat file and shows you exactly which NBT tags are reaching problematic depths. Then you can delete the problematic tags with an NBT explorer.
