Here is the response I received from FANDOM in regards to this issue:

It seems the issue here is the limitations of your device. Typically, when these issues arise it is on very long pages (Just Give Me My Money is 125,000+ bytes) and the editor fails to load the full page due to your device's memory. When this happens, the full page is not loaded which results in odd "undo" actions. I would recommend using an automated service, like AjaxUndo, on these huge pages instead. This will use the API to revert a page rather than loading the editor to do so. You can find information on AjaxUndo here: http://dev.wikia.com/wiki/AjaxUndo

Hope this helps anyone that happened to have this same issue. Also, if you've used the "undo" feature without problems before, it seems like you should be okay.
