All Medium Tanks and Crews Missing/Deleted

Also, they disappeared while I was playing last night, so unless two people can log in to one account at the time, I wasn't password hacked.   Seems like there could be another tank missing, but I hadn't been running all of them. I know the Cromwell (favorite) with the 375% crew is gone, Comet, and the Centurion 1.   I saw another post on this same problem about a month ago, but I can't find it.   I've tried every setting, though I hadn't changed them beforehand, and it was still set to 'all' when I first checked.
