Certain tile entities can't be properly saved (replaced with bedrock)

[TechnologicApe]

I've noticed some blocks don't get saved properly to a schematics file. Blocks like JABBA Barrels and Refined Relocation's Pipes, they get saved as bedrock.

That usually happens when a TileEntity can't be saved on the client side. The log file should contain more information why exactly it fails.

[TechnologicApe]

Is there a way to fix it?

[TechnologicApe]

I read the log,but I don't understand why it wasn't working.

[Lunatrius]

You don't have to understand the log, I just need the stacktrace from the log. Try to save a schematic, the stacktrace will be in the last 100 lines of the log file.

Schematica Saving starts at 581

Looks like JABBA barrels can't be saved client side. Could you try /schematicaSave if it's a SP world?

[TechnologicApe]

Doesn't seem to be working. I've tried:

/schematicaSave <X Y Z> <X Y Z>
/schematicaSave <X> <Y> <Z> <X> <Y> <Z>
/schematicaSave X Y Z X Y Z

Am I missing Something?

[TechnologicApe]

there's supposed to be XYZ in the top two iterations

[Lunatrius]

Typing /schematicaSave will bring up the help text: /schematicaSave <x> <y> <z> <x> <y> <z> <filename>

[TechnologicApe]

OK, I just tried it, it still loads barrels as Bedrock.

In that case there is not much I can do about. It's crashing in JABBA's writeToNBT method which is what vanilla Minecraft uses to save blocks and tile entities into NBT.

java.lang.NullPointerException

    ...

The line it crashes at (worldObj or provider is null (doesn't exist) for some reason...):

BSpaceStorageHandler.instance().updateBarrel(this.id, this.worldObj.provider.dimensionId, this.xCoord, this.yCoord, this.zCoord);

[TechnologicApe]

OK. I'll see what they say over at JABBA

[Lunatrius]

Was there any comment from ProfMobious' side? Because it seems weird that the saving breaks when saving to a schematic but not to the save file even though the same method is used.

[TechnologicApe]

I couldn't find a way to contact them. I never found their Github. However I tried to save a schematic with Refined Relocation and the pipes didn't even save, not even replaced, just didn't save the blocks. The other blocks but not Refined Relocation's.

[Lunatrius]

Pretty sure JABBA is on Bitbucket. Most of the times tile entities fail to save because they depend on something that is not standard or possibly because I forgot to toggle/enable/set something. In JABBA's case I'm not really sure why it happens.

[TechnologicApe]

I've since removed JABBA and replaced it the Storage Drawers, which works, but refined relocation doesn't.
