Explored maps in containers show "Unknown map" after logging out of the game until picked up again

Every time the game closes, all maps lose their description (ID, scale).

The game was on 26.1-snapshot-1 before being updated to 26.1-snapshot-4; the same issue occurs on both versions.

I was able to reproduce this issue as described. (26.1 Snapshot 1 → 4)

Additional testing shows it occurs when updating from
26.1 Snapshot 3 → 4,
1.21.11 → 26.1 Snapshot 4,
26.1 Snapshot 1 → 2
and likely more.

It also appears to affect treasure maps as shown in the photo below. (Tested with 26.1-snapshot-3 → 26.1-snapshot-4)

It seems to affect all types of containers as shown below. (Tested in 26.1 Snapshot 1 → 4)

The Environment field is supposed to only contain PC details.
