After todays update only partial structure gets pasted and when /undo after paste
it says I have to to /paste before /undo.. had to /remove admin everything to clean it up.

Same Here. 😢

Merged post

UPDATE & FYI...
I removed the "Deluxe Christmas Lights" and a "Test Generator" from the build I was trying to copy and paste and it all worked well. It looks like those items on the build were causing the isssue. Now all I have to do is just put those items back after I paste my build where I want it.

Having this issue right now and I have had it in the past.  I'm not getting it to paste back completely ... this base is 3 floor, but not large at all.  Took off all Deluxe lights, no Test Gen and removed the Elevator (have had issues with that in the past).  Still giving the same error, that it hasn't fully pasted in, so I cannot use Undo.  I have changed my radius to 6 and still nothing.
