Can't import saved claim in local world

[rmaliyan]

Hi all! Not sure it's a bug, so posting here. I play on a vanilla server with a few client-side mods. From time to time I export my land claim and import it into a local single-player world so I can test building ideas in creative mode.

This always worked fine - last time I did it was few month ago. But now, whenever I try to import the json, WorldEdit throws an error. Has anyone encountered this before or knows how to fix it? And if this isn’t the right place to ask, where should I post the question? Thanks in advance!

I suspect that we can't help from that snippet. It doesn't reference anything specific to hang off.

I'd recommend the usual:

* Double-check that you have the same Mod list and the same VS version on both source and destination.

* Try a different world and test, in case it is something specific to that world. ie Is it a general problem or a specific problem.

* If you have an older Backup, then test same procedure with the Backup.

* Take a FULL log set (server and client if you have it) to the VS Issue Tracker and log an Issue, along with any details that may help with the ticket.
