I've been running a server for myself and a couple friends on an old laptop for about a month now, and about a week or 2 ago, my laptop froze and I had to abruptly shut it down. I backed up the server and flashed the laptops storage afterwards to get rid of anything that could slow it down or cause it to freeze. When I loaded the server back on to the laptop and logged in, some chunks have either been lowered, raised, have incorrect terrain and sometimes a long line of about 10-15 chunks have a hard time loading but return after some time. But after these missing chunks load back, it will return in a different location in the world.
This is probably a long shot, but is there a way to copy all the player made changes (ie, builds, mines, machines, ect), restart the world with the same seed, then paste all the changes back into the new world? If not, is there other ways to fix these issues without completely starting over?
Note: I couldn't find the missing chunk error while collecting screenshots, so I pulled a picture from google that resembles my issue
Edit: I have found the missing chunks error some time after posting this thread. Google image has been removed and has been replaced with link to my screenshot
