A nice change would be to have vrchat servers hold onto a previous version of a avi or world for a few days after its updated. During that time if the creator needs to they can revert back to that version.

There has been so many times where Ive pushed a update that has a lot of issues to a world/avi and had to quickly try to fix the issues in that update. With this would allow creators like me to just revert back a version while they fix the issues.
