Proficiencies reset

I logged out, normally, after playing for a while on Friday. I log in today to all proficiencies being reset to default, but all learned skills are present.
I did not click on the 'Reset' button(not even sure what it does), and I was using Ender's client at the time.
Anyone else runnning into this?
