Hello! When moving my server from 1.20-rc.6 (the version the world was started on) to 1.20.1, I seem to have made a mistake where I copied the rc.6 content mods over to 1.20.1 accidentally, when I copied over the small handful of 3rd party mods (I simply ran `cp server-old/Mods/* server/Mods/` without thinking, I believe). Upon connecting to the server in this state, the entire world was filled with questionmark blocks, and player data was read as semi-invalid as I was sent back into character creation (but with all of the options I had actually used in character creation selected). I ended up upgrading to 1.20.3 with the proper content mods, and this seems to have MOSTLY fixed the issue... except, now all of our storage in a certain area either displays as questionmark blocks, or empty blocks with the name of "Unknown". Our storage racks are also empty, and any signs that have been placed in the affected area are empty as well (though this is comparatively minor, since signs can be re-written). The only reason I can think of for some being broken and others not, is that the ones that ARE broken are closer to where I was when I connected when things were more generally broken. I unfortunately did not think to make a backup as I didn't think there was a way for a minor version move to be messed up so spectacularly. Worth noting too that I have no mods that should relate to storage functionality, I have BetterHewnFenceGate, ConnectedStairs, PlayerCorpse, ProspectTogether, and th3essentials, and that's it.
Some pictures of the problem:
^ The questionmark blocks here are supposed to be vessels. You'll also notice the tool racks are empty, even though they previously I believe contained our one pickaxe and saw
^ In this photo they're supposed to be crates, and you'll also notice the blank sign
^ Working vessels, just a little ways away from where the broken storage is
I also didn't manage to get a photo of it, but our reed baskets in the affected area are what show up as empty but highlightable blocks with the name "Unknown"
