Front Bearing on Medusa MR-036-060-2000V2-5

Today I had the front bearing on my Medusa MR-036-060-2000V2-5 just disappear..I was running my Brushless Mugen X5-T when all of sudden it stopped..Everything was running great..Temps were very low, power was great..The gearing seems to be right on..I am running on 4S as well..Anyone else have any issues with the front bearing just blowing out of the medusa motor..I think it was just a freak incident..I replaced it with a new Medusa motor and so far no issues..Hopefully I can get the motor warranteed.. Just want to see if anyone else has had this happen..BTW here are some pics of my Beast..
