Versions

1.15, 1.16

Problematic behavior

[Server thread/ERROR]: Block at 51, 67, -120 is Block{minecraft:stone} but has net.minecraft.server.v1_16_R3.TileEntityChest@314c3a56. Bukkit will attempt to fix this, but there may be additional damage that we cannot recover.

When a chest/container is replaced via WorldEdit, the server prints out a messages in the console which seem to have no purpose. After talking to WorldEdit devs, they stated this would not be a WorldEdit error, which can also be read here: https://github.com/EngineHub/WorldEdit/issues/1312

Expected behavior

No spam should be printed in the console.

How to recreate

Select a chest with WorldEdit and use //set stone

Notes

The message doesn't occur on paper 1.16.5, so they seem to have introduced already a fix which probably might be worth to have in Spigot directly instead.
