Parts randomly deleted on team create, need help restoring

Been working on a huge map for the past couple days with my friends - didn’t make any backups, my mistake. Came back to my computer one time to see random parts and models have been indiscriminately deleted in the game (around a quarter of the game).

Is there any way to restore the lost models and parts? We all checked auto-saves on our computers and couldn’t find any that went back far enough. Does team create allow us to revert?

Fixed, found old version in “configure place” and reverted
