Fantastic work on the updates, I really like the new features in v2.2. However I have a severe problem (tested with only sync and thermalexpansion). When syncing across dimensions, you lose access to the original shell you synced from. It appears to be serverside, as rejoining an SSP world fixed it, but rejoining SMP did not, locking me out of my main body :(

I'm not sure if this is related but when trying to sync from a storage in the nether to a newly constructed shell in the overworld, instead of being put in the new shell, I was given a new body in the middle of nowhere in the overworld. I spawned a new storage and did not have access to the overworld shell (which I later found to still be there), but still had access to the nether shell, almost the reverse of the above issue.

Did you update from a 2.1 world to a 2.2 world? There was a change with how shells registered and chunk loaded themselves which may have caused issues on using older worlds with the new version.

Yes. Ah I see, unloaded chunks would make sense. Is there a possible ingame solution? Don't really want to give up on the hundreds of hours everyone has put into the world.

You could try just breaking then placing down the constructors/storages again, that might work. If not then it is possible it is part of a bigger issue
