no other errors or warns

other players can interact with chests and other containers, but can't break/place blocks.

Only chunks that are considrered "dirty" will be removed (aka, chunks with blocks)
If you edited the chunk without letting SSB know, it will not know that the chunk is dirty

okay, I repeated everything and placed a block by hand in every chunk. And all chunks are deleted 👍 .
But the blocks in the chunk in the second picture with the redstone in it were placed by hand too and not with FAWE or other plugins and that chunk was not deleted.
