How to restore a chunk that failed to load

[CBFASI]

Bug caused it, after a solution.

 

A few times now the game has 'failed' to load a chunk, normally part of the base/home and I end up rebuilding..

The game replaces the failed chunk with what was there by default.

Sometimes its just scenery, but in this last case its the original inside of the building, taking away all my storage boxes and other interior changes I made.

 

I have noticed however that a pair of files get created in the Region folder in the saves, in this case they are

 

error_backup_45_41.comp.bak

error_backup_45_41.uncomp.bak

 

If there is anyway to restore the chunks then I would be grateful, I do have a copy of the files from 3 hours earlier, so not end of world but I would prefer to not of lost it.

 

Btw log data...

i had the same thing happen, and it also impacted the core interior of my base. it was reset to the original terrain blocks. meanwhile all other adjacent checks are just fine like nothing happened. if there's a way to restore those chuck backup files into the game that would be awesome.
