Anything else?

It's on a Minehut server, so I'm not sure if that will affect anything with this bug report.

Can't reproduce it anymore with v6.11.1, it works as intended with all the items in that moved shulker box. Moved the plot with a shulker in it containing the items I put into. The result:

Not 100% sure if there is an edge case, but I tried it twice in different directions, tried it with some iterations and nothing bad happened
