Stephanie, it's probably happened to most of us a few times. This is NOT condoned by WikiTree or the community here. Although we all have a lot of editing access to a lot of profiles here, we are expected to communicate with other potentially interested parties before making any significant changes.
You've been given good advice already about how to deal with this situation, but I just want to set your mind at ease a little, if I can. If you click the Changes tab, you'll see a list of all changes made to a profile and can click any of them to display the before and after versions, showing EXACTLY what was changed. You also have an option to restore a profile to any previous state, so all the previous work that had been removed isn't lost.
