Also the orientation doesn't seem to be applied correctly..?

edit: My brain was in stream mode so I forgot to mention / test important details. Apologies!

Which mod are the chests from and what is the mod's version? What is your Forge version?

Assuming she's talking about my modpack, the chests are from Quark. The versions are:

• Minecraft 1.12.2
• Forge 14.23.1.2559
• Quark 1.4-118
• Charset 0.5.0.88

(we play on a server, so these should be correct)

Could not reproduce, although I was using Quark 1.4-120 and Forge 2552.

Is there anything interesting in the log? Any coremods you think might be a culprit?

Wait. I just reproduced it. Whaaaat.

Do tile entities require special carry registration? Vazkii only registers the blocks, and stores the chest variant in tile NBT. See: VariedChests.java#L76-L77 and TileCustomChest.java

@InsomniaKitten No.

Okay, I got it to reproduce, but only if you place the Quark chest next to another Quark chest.

Okay. I found the issue. It's related to a special hack implemented for vanilla chests, but Quark doesn't validate what ItemStack it receives in onBlockPlacedBy - well, nobody expects it to, so it's fine!

Working on a fix.
