The latest update has messed everything up. All my multiple day events have change the dates on the own and only show up on the first day. For example, if I put an event on February 12 and 13 for all day which repeat for all time, the date will automatically change to Feb 12 through Feb 11 within a few minutes and therefor only show up on whatever the first day was. Also, a few events have randomly disappeared according to my wife.
