Strangely "Last changed by" is incorrect.
I modified 10+ tables by dropping and creating an index. On two tables the index didn't exist and I had to create it. Big was my surprise that those two tables had a different user than me set as the owner of the change. It is even more strange that each table has a different user mentioned as the change owner.
No big issue, but still something weird. And perhaps better if the change is linked to the user doing the change.
