Pre-existing chests invisible, overlapping

Can you upload the world somewhere (dropbox/mediafire/mega/anywhere you are ok with) so we can test with it?

I've encountered the same problem (in 17w47a and b, and 17w48a) with four double-chests on my world: two of them (both west-facing) display a single chest on the right with an invisible type: left; two (both north-facing) display a double chest on the right with an overlapping single chest on the right. In all cases, opening the chest displays the single-chest inventory of whichever side was clicked.

This is one of several problems when making a distant upgrade. See Grum's comment in a currently private bug. MC-122331 Please keep open or find the duplicate.

"Thanks, seems to happen when you load a world from 1.10 and older straight in 1.13 snapshots. If you'd load it in 1.11 and 1.12 then all is fine.
Sadly a known but severe issue in the upgrade system, going to need quite a rewrite on it. But at least I might know how now!"

To clarify, i'm encountering the issue after updating from 17w46a.

After some testing (replacing the chests in a clean copy of the world in 17w46a, then updating to 17w48a: replaced (and re-filled) original chests; crafted entirely new chests; placed chests in different order (left first, right first, both on the ground, one on the ground one on the wall, one on the ground one on the side), replaced all blocks in contact with chests), it looks like the glitch is with the location, not the chest or placement.

I created a new world with the same seed in 17w46a, teleported to the location of the bugged chest nearest the surface and placed a double chest in the same location facing the same direction; updated the world to 17w48a, and the chest was bugged (double chest and single chest overlapping ).

I went back to the 17w46a copy and placed the chests in the same spot but facing the opposite direction and then updated again; the chest was still bugged, but this time it was a single chest with an invisible left-side.

Seed:
-2984774574616727810

Chest placement:

-10587 68 -3567 and -3568

Safe teleport location:

-10597 73 -3568

Updating from snapshots to other snapshots is not supported.
Please check if it's also the case when updating from 1.12.2 and whether the symptoms are the same as described in the report.

Confirmed: created a new world in 1.12.2 at seed -2984774574616727810, teleported and placed chests, opened world in 17w48a; east-facing chest was displayed as a single chest and an invisible left-side chest.

MC-122468 Another report for clean up or the person's credibility. Watching for these.

Much thanks to pykaxe!

@unknown, all bugs caused by the debug stick won't be fixed. Also, this is unrelated to this report, which is about upgrading from old worlds.

if i made a new report they would say it already exists _

If you were to make a new report, we would not resolve it as duplicate of this but would resolve it as"won't fix."
